Combined with satellites, radar gives forecasters the ultimate tools to provide accurate forecasts and advanced severe weather warnings.ĭoppler Radar gets its name from the Doppler Effect. Doppler Radar gives forecasters the capability of providing early detection of severe thunderstorms that may bring strong damaging winds, large hail, heavy rain, and possibly tornadoes. This is what meteorologists use to see rain or snow.ĭoppler Radar detects precipitation intensity, wind direction and speed, and provides estimates of hail size and rainfall amounts. It stands for Radio Detection and Ranging.

Radar is an electronic instrument, which determines the direction and distance of objects that reflect radio energy back to the radar site. City lights, fires, effects of pollution, auroras, sand and dust storms, snow cover, ice mapping, boundaries of ocean currents, energy flows, etc., are other types of environmental information collected using weather satellites. These meteorological satellites see more than clouds and cloud systems.

Satellites can be either polar orbiting, seeing the same swath of the Earth every 12 hours, or geostationary, hovering over the same spot on Earth by orbiting over the equator while moving at the speed of the Earth’s rotation. If the relative humidity is low, we can feel much cooler than the actual temperature because our sweat evaporates easily, cooling us off.Ī weather satellite is a type of satellite that is primarily used to monitor the weather and climate of the Earth. As a result, we feel much hotter than the actual temperature when the relative humidity is high. If the air is at 100-percent relative humidity, sweat will not evaporate into the air. The process of sweating is your body’s attempt to keep cool and maintain its current temperature.

Humans are very sensitive to humidity, as the skin relies on the air to get rid of moisture. Relative humidity is the ratio of water vapor contained in the air compared to the maximum amount of moisture that the air can hold at that specific temperature and pressure. Humidity is the amount of water vapor in the air. The higher the dew point, the greater the moisture content is in the air. The dew point temperature changes only when the moisture content of the air changes. The dew point is the temperature at which water starts to condense out of a particular air mass.

A low pressure system is represented as a big, red L. When viewed from above, winds spiral into a low-pressure center in a counterclockwise rotation in the Northern Hemisphere. A high pressure system is represented as a big, blue H.Ī low pressure system is a whirling mass of warm, moist air that generally brings stormy weather with strong winds. When viewed from above, winds spiral out of a high-pressure center in a clockwise rotation in the Northern Hemisphere. Weather symbols are used on my weather maps as shorthand for the conditions at weather observing stations.Ĭlick Here to see a complete list of all the weather station symbols.Ĭlick Here for an easy print out of the different weather station symbols.Ī high pressure system is a whirling mass of cool, dry air that generally brings fair weather and light winds. By using these methods, reasonable accurate forecasts can be made up to seven days in advance. Weather forecasting involves a combination of computer models, observations, and a knowledge of trends and patterns. Weather forecasting is a prediction of what the weather will be like in an hour, tomorrow, or next week. How do meteorologists forecast the weather?
