a scientist who studies the atmosphere using vairous insturments, computers and models to make weather maps.
water in the solid or liquid form that falls to the earth's surface from clouds
The state at the atmosphere at a given place and time regaurding heat, cloudiness, relative humidity, sunshine, wind, precip.etc,.
the weather conditions prevailing in an area over a long period of tme
rain or drizzle that freezes on contact with the earth's surface. Results when rain or drizzle falls from a mild layer aloft into a shallow layer of below freezing air.
partially melted snowflakes that refreeze prior to striking the earth's surface. Results when partially melted snowflakes fall from a mild layer aloft into a deep layer of below freezing air
a type or pecipitation that consists of an assemblage of ice crystals. Results when temperatures remain blew freezing from the cloud all the way down to the ground
a type of precipitation that consist of water droplets from 1-6 mm in diameter. May result when temps. are above freezing from the cloud to the ground or when snow is falling from a cloud melts as it encounters warm air.
precip that consists of water droplets from 0.2-0.5 mm in diameter. May happen when temps are above freezing from the cloud to the ground or when snow falling from a cloud melts as it encounters warm air.
low pressure weather storm systems that occur in the middle latitudes of the Earth(oputside the tropics) that are connected with fronts and horizontal gradients in temperatue and dew point producing anything from cloudiness and mild showers to heavy gales and thunferstorms. Air is rising and winds are counter clockwise around this type of system.
a large-scale circulation of winds around a central region of high atmospheric pressure clockwise in the Northern Hemisphere. Air sinks within this type of system.
a line that connects points of equal atmosheric pressure on a weather map.
in weather forecastin, a cluster of meteorological data plotted on a map indicating the weather information at a particular reporting station
a special type of weather map that povides a view of weather elements over a geographical area at a specified time based on information from ground-based weather stations. These maps are created by plotting or tracing the values of relevant quantities such as sea level pressure, temp, and cloud cover onto a geographical map to help find features such as weather fronts.
a prediction or estimate of future atmospherioc conditions
a representation of a system often times on a smaller scle that can be used to help simplify and/or make predictions
an instrument used to measure wind speed
an instrument used to measure wind direction
