DOPPLER RADAR: Weather radar that measures the direction and speed of a moving object (such as drops of percipitation), by determining whether the atmospheric motion is horizontally toward or away from the radar.
Weather forecasting includes the use of objective models based on certain atmospheric parameters, along with the skill and experience of a meteorologist.
Generally, with the passage of a warm front, the temperature and humidity increase, the pressure rises, and although the wind shifts (usually from the southwest to the northwest in the Northern Hemisphere), it is not as pronounced as with a cold frontal passage.
The AdvancedWeatherInteractiveProcessingSystem (AWIPS) is a technologically advanced information processing, display, and telecommunications system that is the cornerstone of the National Weather Service (NWS) modernization and restructuring.
AWIPS is an interactive computer system that integrates all meteorological and hydrological data, and all satellite and radar data, for the first time, and enables the forecaster to prepare and issue more accurate and timely forecasts and warnings.
Through the implementation of AWIPS, the NWS will meet its mission "to provide weather and flood warnings, public forecasts, and advisories for all of the United States, its territories, adjacent water and ocean areas, primarily for the protection of life and property" more efficiently and effectively.
