What are the four types of weather observations that meteorologists make?

There are four types of weather observations: surface, upper air, radar, and satellite.

Why are weather observations made at airports?

Surface weather observations have traditionally been taken at airports due to safety concerns during takeoffs and landings. This is useful in calibrating instruments and designing aircraft, and is used to reduce a station’s pressure to sea level pressure (SLP) where it can then be used on weather maps.

What observations are important to meteorologists?

Temperature, humidity, precipitation, air pressure, wind speed, and wind direction are key observations of the atmosphere that help forecasters predict the weather.

What are the main sources of weather observations?

The sources are:


How do meteorologists make weather predictions?

They collect and share data to help improve forecasts. Some of the tools they use include barometers that measure air pressure, anemometers that measure wind speed, Doppler radar stations to monitor the movement of weather fronts, and psychrometers to measure relative humidity.

How do I find weather information on a flight?

TIBS can be accessed by calling 1-800-WXBRIEF or one of the local numbers listed in the FAA Chart Supplement Publications. In-person briefings give the pilot access to a specialized aviation weather briefer who can give the pilot weather information for specific areas or routes of flight anywhere in the country.

How do airports collect weather data?

The Automated Surface Observation Systems (ASOS) provide the nation’s primary surface weather observations from airports across the U.S. Aircraft are used to collect weather data over land and sea.

Where do airports get their weather reports from?

METARs typically come from airports or permanent weather observation stations. Reports are generated once an hour or half-hour at most stations, but if conditions change significantly at a staffed location, a report known as a special (SPECI) may be issued. There are stations that make regular reports more often.

How do meteorologists predict the weather?

Today, meteorologists use complicated mathematical equations to help predict the weather as part of a process known as numerical forecasting. Numerical forecasting requires powerful supercomputers and tons of observational data from land, sea, and air weather stations around the world.

How do meteorologists gather and use data about the weather?

Observational data collected by doppler radar, radiosondes, weather satellites, buoys and other instruments are fed into computerized NWS numerical forecast models. The models use equations, along with new and past weather data, to provide forecast guidance to our meteorologists.
