Why Do We Measure The Weather?

Measuring the weather
Measure the weather

Why do we measure the weather? Understanding the weather has served great significance over humanity, from planting crops to setting out into the ocean. Predicting how the environment behaves has guided everyday life up to the present.

However, with modern technology, weather measurement and monitoring have grown beyond the need to inform livelihood. It has grown to include efforts to understand how our collective actions have led to where we are now and, more importantly, where we are headed in the future. Here are some of the most compelling reasons why we measure the weather.

1. Why Do We Measure The Weather? People

Most activities depend on the weather conditions, from minor daily decisions to long-term plans. It helps people decide on what they’ll do, the clothes they wear, and even the food they’ll prepare later on.

Weather forecasts have become a staple in regular news programs as it gives you the heads up you need for the upcoming day. Whether you’ll need a raincoat or a hat, or whether it’ll be safe to take the ferry or not, all depends on what are the expected conditions for today. With access to better technology and larger data sets, weather forecasting has become more accurate and more reliable. The latest weather updates are available right from your fingertips, allowing you to observe weather conditions anytime.

This capability also applies to long-term planning. Despite the drastic changes in meteorological patterns due to climate change, forecasts remained relatively accurate. Our ability to predict weather and climate conditions continue to keep up with the changing trends thanks to evolving weather measurement and monitoring instruments.

2. Livelihood

As mentioned, livelihood has always been a critical driver for measuring and predicting the weather. Many industries heavily depend on climate and weather, as they’ve done for hundreds of years.

Humanity learned to settle in one place when they learned how to plant crops for sustenance. Since then, it has become imperative to know when rain falls, or droughts are more likely to occur. These pieces of information are essential in finding the best time to start planting and when to harvest crops. Although humankind has nearly perfected the cycle of the seasons and the planting schedules, rapid changes and unstable conditions threaten the farmers’ ability to plant and harvest. 

Aside from planting crops, animal domestication is another field that requires a good understanding of the weather. Like crops, livestock is also an essential part of the human food supply. Being unable to care for animals could upset their store, causing food security issues that can threaten many lives down the line. By having a good grasp of weather conditions, people in these industries can carefully plan when to allow the animals to graze or stock up on the animal feed.

3. Transport

Before, weather prediction told humans when it was safe to set off on boats and go fishing. The same idea continues today but on a much larger scale—weather measurement and monitoring impact a vast global industry, from small fisherfolk to large shipping vessels.

Industrial fishing vessels, cargo freighters, and even oil tankers depend on modern technology to safely and efficiently ply their trades. It is essential to know if there’s a storm brewing down their path days or weeks in advance to avoid unnecessary risks. Modern marine vessels now use weather routing technology, which uses the latest weather information available to guide shipping routes and travel plans. Networks of sensors and monitoring systems provide insights on wind and currents, guiding navigators and sailors of weather conditions ahead of them.

The importance of weather prediction is not limited to marine transport too. Airlines also need timely and accurate information on the environment. Pilots, like sailors, need to know what lies ahead. Irregular or unstable air currents cause turbulence, while potential rains also affect visibility in the sky. 

4. Science

By measuring the weather, we learn more about it, which allows us to develop better and more accurate systems. Before, people recorded how the phases of the moon or fluctuations in airflow give hints on upcoming tides and storms. We have sensors installed on ocean buoys or weather balloons–scattered around the world to collect information without the need for an actual person to go and manually monitor those places.

Furthermore, technology has enabled people to gather more data and process them more efficiently. Artificial intelligence and machine learning are becoming increasingly important because of their ability to handle large amounts of data. With these tools, people can now make projections about meteorological conditions far into the future.

The same technologies are being used to assess how our actions impact the environment. Visualizations of past and present carbon emissions now help explain how climate change continues to evolve and how it threatens our future. In doing so, experts can recommend what collective actions are available to mitigate or even reverse this phenomenon.

Final Word

Measuring the weather is a vital endeavor. It affects our immediate plans and activities and our entire future as a species. As we better understand how the world works, we’ve also found ways to use it for our development. Thanks to predicting weather far into the future, we’ve had entire fleets of aircraft and networks of ships traveling in perfect unison.

More importantly, technology has allowed us to finally see how we impact the environment and how it affects us in return. We can identify options on how we can reverse the damage done and secure the world for future generations.

Weather Observation Equipment and The Social Influences It Has Made

History of Weather Observation Equipment and The Social Influences It Has Made
History of Weather Observation Equipment and The Social Influences It Has Made by Bash Sarmiento

Weather Observation

Weather observation; It was not until the advent of the weather instrument that meteorology became a science. Meteorology was a key topic of discussion among the Greek philosophers, and many of those later involved in weather forecasting used their ideas. 

Now, weather instrumentation allows us to predict and measure to the hour and in real-time. To appreciate this, we need to understand the history of weather observation equipment and how society influenced its development.

Instrumentation In Ancient History

Early civilizations monitored seasonal changes in the weather using recurrent astronomical and meteorological events. Babylonians attempted to predict short-term weather changes around 650 B.C based on optical phenomena such as haloes and clouds. 

In 300 B.C., Chinese astronomers created a calendar where each holiday was associated with a particular kind of weather.

For centuries, forecasts have been produced based on weather lore and personal observation. By the end of the Renaissance, scientists realized the speculations of natural philosophers had become insufficient. 

Further knowledge was needed to understand the atmosphere better. The atmospheric properties were measured using instruments, such as moisture, temperature, and pressure.

Invention of Weather Instrumentation

In the mid-fifteenth century, Nicholas Cusa described the first hygrometer design in western civilization. The first standard rain gauge was invented in 1441 by king Sejong’s son, Prince Munjong. In Korea, these were used to assess land taxes based on a farmer’s potential harvest during the Joseon Dynasty. 

In the mid-17th century, Evangelista Torricelli invented the mercury barometer by an Italian mathematician and physicist. There was also the development of a reliable thermometer simultaneously, founding the basis for modern weather measurement. While gas thermometers were available even during Galileo’s time, they were unreasonable and defective.

With a mercury-type thermometer, Gabriel Fahrenheit developed a reliable scale for measuring temperature in 1714. In 1742, a Swedish astronomer named Anders Celsius proposed the ‘centigrade’ temperature scale. 

Horacio Benedict de Saussure was the first to demonstrate a hair hygrometer in 1783. A system of grading wind speeds was introduced in 1806, devised by Francis Beaufort.

Marine weather sensor technology has advanced rapidly over the past half a century. These can provide visual images and data that can be used to calculate temperature and humidity profiles and other environmental variables.

Modern Weather Observation Equipment

With the development of weather instrumentation came the introduction of satellites in 1958. Today, these satellites give us global coverage and high-time resolution data. This data is used to develop accurate weather forecasts, which are also used in disaster management. 

The advent of weather observation equipment led to significant improvements in society, especially concerning agriculture. With accurate predictions and measurements, farmers could plan their planting and harvesting strategies more effectively. 

With photocells and other technologies, weather stations are used for many different applications. Weather stations allow meteorologists to observe critical data, such as temperature, humidity, rainfall, wind speed, wind direction, barometric pressure, and current barometric pressure trends. 

Recently, radar network sensors have been developed. These can detect and report the movement of precipitation. The advent of better weather observation equipment has led to better weather forecasts, which has enabled more individuals to plan their daily activities accordingly.

Weather instruments such as weather balloons, remote sensors, and ground-based weather stations provide us with weather information. These sensors provide temperature, pressure, humidity, wind, rain, snow, solar radiation, and clouds. Weather sensors are also used to develop short-term weather forecasts, which meteorologists then use to develop longer-term forecasts. 

Social Impact of Weather Observation Equipment

Meteorology plays a crucial role in society today. From predicting the weather, forecasting disasters, and providing weather warnings, weather forecasting has come a long way. It contributes to planning, transportation, agriculture, and industry.

With the advancement of weather instrumentation came the improvement in weather forecasting. The improved weather forecasts led to more precision in activities like agriculture, which led to an increase in crop yields.  

Weather stations are also used to measure air pollution and to predict hurricane movement. These technologies also led to satellite networks and radar networks, which provide information about atmospheric conditions to meteorologists.  

The advent of weather instrumentation led to more precision in activities like agriculture, which led to an increase in crop yields. It also led to satellite networks and radar networks, which provide information about atmospheric conditions to meteorologists.

Farmers tend to plant and harvest their crops based on seasonal weather predictions. Otherwise, they will plant when there is insufficient rainfall and harvest when the rains start. This can result in crops being ruined. They also use weather forecasts to determine when to apply fertilizer. By understanding the amount of rainfall, farmers know when to fertilize their crops.  

Weather observation equipment is also critical in aviation. Air traffic controllers use reports produced by weather equipment to make crucial decisions. They also use this information to plan operations.  

Weather observation equipment is also used in the transportation industry, whether it’s for land, sea, or air transport. Airlines, for example, use weather observation equipment to determine flight levels. This allows them to plan routes based on factors such as wind.

Future of Weather Equipment

The field of meteorology is constantly evolving. New technologies are being developed, leading to better weather forecasts. New weather mapping systems are being designed to contribute to accurate weather forecasts. 

The advent of new weather observation equipment will lead to more accurate weather forecasts. This will lead to better planning, which will benefit agriculture, aviation, and the transportation industry. 

With climate change and global warming, extreme weather has become the norm. We rely heavily on weather equipment to detect and report climate changes. Weather stations use sensors to detect climate change, which is used to improve forecasts. 

New technology is being developed. These include sensors, software, and networks. These are being developed to improve the accuracy of weather forecasts. They also allow for better monitoring of the environment. 

Artificial intelligence (AI) and machine learning provide significant benefits for weather forecasters. With AI, forecasters can process more data more rapidly, which helps them develop more accurate forecasts. With machine learning, forecasters can obtain more data about past weather, which helps them identify patterns and predict future weather.   

Predicting weather better and more efficiently will improve our day-to-day lives. Weather equipment will continue to be developed to enhance our ability to make better weather predictions. 

Final Thoughts

The importance of weather instrumentation is that it provides real-time data, allowing meteorologists to develop accurate weather forecasts. This data is also useful to farmers, the aviation industry, and the transportation industry.

Weather instrumentation will continue to play an essential role in our lives. New technology is being developed, leading to better weather forecasts. Appreciating the history of weather equipment yesterday can help you build on a better future tomorrow.

How Weather Watching Originated

Weather Watching history with Instromet by Bash Sarmiento

Weather over London

Weather watching is an essential scientific practice. It lets us prepare ourselves for what nature decides to bring us on that day. It’s often taken for granted that for the longest time, humans had no way of telling what the weather was going to be like past hunches. The history of weather watching is fascinating and it would be a disservice to not talk about it. So, that’s exactly what we’re going to be doing today.

What is Weather Watching?

Weather watching is the in-depth observation of weather patterns using quality-controlled prediction models. Weather watching can be done on either a local or global scale. Without the comprehensive weather reports provided by weather watchers, people would not be able to prepare themselves for sudden weather changes.

Weather watching is done through observations of pressure, moisture, wind speed, wind direction, and temperature. The consistency of all these factors since the earliest weather observations has helped in making predictions much easier. In addition to that, the advancements in weather forecasting technology have made weather updates more accurate than ever before.

History of the Radcliffe Observatory

The Radcliffe Observatory is one of the earliest, if not the earliest, weather observatories ever recorded.  It has records from as far back as 1772, which gives us insight into what the weather was like hundreds of years ago. The Radcliffe Observatory boasts the longest single-site weather records in the UK and one of the longest in the entire world. 

Its creation was thanks to one Dr. Thomas Hornsby (1733-1810), a Savilian Professor of Astronomy. He was entrusted with the funds for the construction of a large observatory as well as all the proper equipment. The building began in 1772 by the Radcliffe Trustees, who promptly gave Hornsby the title of Radcliffe Observer.

The research they took started with observations of air temperature, but surprisingly enough, for astronomical refraction, not the weather. Slowly but surely though, Hornsby began observing the weather until the date of his death in 1810. All of these records are recorded in the annual volumes of the Radcliffe Astronomical, which began in 1849.

For equipment, they would often use very rudimentary thermometers. However, the observatory was always kept up to date with the latest in forecasting technology. In fact, many of the innovations for weather forecasting in the UK stemmed from Radcliffe. Famous institutions include Kew, Greenwich, and Oxford.

The 1850s was when the records started becoming more in-depth and frequent. Photographic and autographic instruments were used to provide more consistent records of rainfall, wind, and temperature. 1881 to the present is complete and reliable, as dictated by the Met Office.

Radcliffe Observatory’s constant observations since its inception to the present day have been a major benefit to weather watching. The link it provides between the weather from hundreds of years ago and the weather today is essential to understanding our world.

History of Weston Park Weather Station

Another important weather station in the UK showcases the importance of weather watching to the general public outside of scientific advancements. The creation of Weston Park Weather Station is because of an outbreak of bacterial infections in Sheffield back in 1882.  

In fact, this particular use for weather watching is still applied to this day with the recent COVID-19 epidemic. By analyzing the temperature and humidity in the different areas infected with COVID-19 (or not),  scientists should be able to determine when an outbreak may next occur and act accordingly.

Elijah Howarth, dubbed “The Prophet”, believed that understanding weather conditions, especially temperature, would help let the local doctors know if an outbreak was going to be likely. The station’s first equipment was bought with the help of a small department in the Board of Trade. 

That small department would soon become the Met Office, the main meteorological authority in the UK. Weston Park is one of the Met Office’s first official weather stations for this reason. Its longevity, along with Radcliffe, is why it’s considered one of the most important weather stations in the entire country. 

To this day, Weston Park continues to record weather patterns using various techniques and equipment such as state-of-the-art thermometers, barometers, and weather drifting buoys.

Weather Watching – Conclusion

The history of weather watching is an important period in scientific history. There’s a lot of benefits to be learned from how observations were recorded back then as opposed to how the weather is recorded now.  Determining what the climate is going to be like in the future is important not just for scientific study, but for socio-economic reasons.

After all, the weather affects more than just forecasting equipment. Important activities such as farming, disaster prevention, and travel are all reliant on accurate weather predictions. To constantly improve our current weather forecasting technology, it’s important to look back on how our predecessors did things with much less equipment.
