Meteorologists predict weather and climate, study, analyze, interpret, and provide weather reports and weather patterns on a day-to-day basis.

Atmospheric science deals with the Earth's atmospheric conditions and its phenomena, such as the precipitation of typhoons, tornadoes, thunderstorms, rain, and snow. It also deals with variations of temperature, moisture, wind speed, wind direction, and similar patterns that produce distinct weather conditions.

Meteorologists predict weather forecasts using complicated mathematical equations. They use an anemometer to measure the speed and pressure of the wind. Instruments also include barometers (one of the most critical instruments in weather forecasting), rain gauges to measure rainfall, wind vanes to measure wind speed, thermometers to measure temperature, weather balloons, and weather satellites to compile the data required for forecasting.

Observational weather data gathered by tools like Doppler radar, radiosondes, weather satellites, buoys, and other instruments are formatted and transmitted to the National Weather Service or such relevant services where they use computerized numerical forecast models. These models use new and past data, utilizing various equations, to provide weather forecast guidance to our meteorologists. Based on the collection of quantitative data about the current state of the atmosphere on the land and ocean, meteorologists project the atmosphere at a given place.

The barometer that measures atmospheric pressure helps meteorologists predict weather patterns for a given time and location. They provide warning signals about the slight changes in the pressure of the atmosphere. These forecasts provide weather warnings used to protect life and property and are also used to plan activities and fulfill them. Temperature is predicted by meteorologists using weather balloons having weather packs to measure the temperature, speed and wind direction, and air pressure in all the tropospheric layers. Short forecasts are approximately accurate up to (80-90%). A more extended weather forecast above nine days is accurate about half the time.

Tools Used By Meteorologists To Predict The Weather

Meteorologists are responsible for monitoring the impact of weather and the patterns of temperature in the past and current times. However, the tools used have changed due to technological advancement, and our scientists now use efficient means to use the collected data. Technologically advanced tools make faster and more accurate predictions and forecasts.

Doppler radar helps detect the rotation of the thunderstorm clouds, the strength of the wind and the direction, airborne tornado rubble, and all kinds of precipitation. They generate velocity data of the distant entity and analyze how the object's motion has altered the frequency of the returned signal from the entity.

Typical weather satellites are used to monitor our planet from the vastness of space to collect the data for analysis by our scientists. The polar-orbiting satellites closely monitor the surface of the Earth, taking six to seven detailed pictures per day. In contrast, the geostationary satellites remain stationary over the exact location in space and take clear pictures every half a minute. Deep-space satellites, on the other hand, are positioned towards the sun in order to observe powerful solar storms and other relevant space weather. 

In short-term weather forecasting, satellites are critical and provide an early indication of a developing thunderstorm and show the location where the cumulus clouds are forming. If the conditions are appropriate, these cumulus clouds proliferating into cumulonimbus clouds are tracked using detailed images. 

Weather balloons fitted with radiosondes operate at a frequency of 403 MHz or 1680 MHz and float to the upper stratosphere to collect upper air data, which is measured twice a day in the vertical layers of the atmosphere. Hundreds of radiosondes are launched worldwide on a day-to-day basis and are an essential source of data.

The radiosondes dropped from airplanes are called 'Dropsonde'. They measure and calculate the variables like wind speed and direction, cosmic ray readings at high altitudes, geographical position, altitude, temperature, pressure, and relative humidity.

The automated surface observing systems collect important data about the weather conditions and patterns on the surface of the Earth. Weather stations from around the world provide data about the sky conditions, temperature, precipitation, and surface visibility at an approximate frequency of around a dozen times in one day. Information about the temperature, rainfall, and snowfall is shared with others to improve forecasts and warnings based on the additional data. People report data to their systems to be shared with others.

The data from radiosondes, satellites, doppler radar, service stations, and other instruments are updated on the supercomputers. The supercomputers collect data, analyze data, and process these data across the entire world. These supercomputers are essential in modern forecasting. The output provides weather forecasts and helps guide meteorologists into accurately providing data.

The advanced weather information processing system (AWIPS) provides a visual outlook on the output prepared by the supercomputers. Once the meteorologists prepare their forecast, the AWIPS moves on towards generating weather graphics about dangerous weather and communicating warnings to the public. 

Real-time weather information is beneficial for farmers to protect their crops from bad weather.

Factors Taken Care By Meteorologists To Predict The Weather

 Weather forecasters determine the current conditions of the data collected, particularly the temperature, humidity, wind, and how the atmosphere will evolve in the future. Many factors are combined to influence the weather of any land area. The significant factors are bundled below:

Air Temperature, air pressure, the humidity of the air, cloud cover, the kind of precipitation, spend, and the direction of the wind. 

The variations in solar radiation with Earth's tilt, the orbital distance from the sun and latitude, and the quantum of water are more factors.

The impacts caused by air-mass differences like cyclones, thunderstorm clouds, and hurricanes are a major factor as well.

The varying wind and air mass patterns caused by the distribution of air pressure over the land and nearby oceans is a factor too.

Skills Required By Meteorologists To Predict The Weather

Meteorologists study, analyze, interpret, forecast weather and climate, and provide daily weather reports.

To start a career in meteorology, you must be exceptionally good at math, chemistry, physics, computer science, and social studies. Being a math-based profession, the subject requires a great understanding of calculus and physics, and any aspirant must have the ability to use logical reasoning and pay attention to detail. The critical skills for meteorologists include analytical skills, teamwork skills, genuine interest in weather systems, interpersonal skills, problem-solving skills, written and oral communication skills, computer literacy, and mathematical abilities. 

Did You Know...

The National Oceanic and Atmospheric Administration (NOAA) is a scientific and regulatory agency in the United States that provides accurate forecast data and environmental predictions based on computer models.

They monitor, forecast, and supply information regarding the ocean's weather conditions, chart the seas, conduct deep-sea exploration, and manage the protection of endangered species and marine life. NOAA's national weather service provides weather warnings and forecasts about the state of the oceans and the atmosphere. The Global Forecast System (GFS) is operated by the National Weather Service in the United States. They provide a weather prediction system based on numbers with the help of a global computer model. Computer weather models, also known as numerical weather prediction (NWP) models, have revolutionized the science of weather predictions by creating a virtual planet. They can predict what the weather will be like in the future. Hazardous weather watches are human surveillance or doppler radar signals observing severe storms that are expected or already occurring. Atmospheric research scientists examine how the weather and climatic conditions affect human activity and the Earth in general.
