What does a station model look like?

In meteorology, station models are symbolic illustrations showing the weather occurring at a given reporting station. Elements in the plot show the key weather elements, including temperature, dew point, wind, cloud cover, air pressure, pressure tendency, and precipitation.

What is a station pressure?

STATION PRESSURE: This is the pressure that is observed at a specific elevation and is the true barometric pressure of a location. It is the pressure exerted by the atmosphere at a point as a result of gravity acting upon the “column” of air that lies directly above the point.

What pressure levels are mandatory to report?

When the upper atmosphere is observed, there are specific pressure levels that are always reported. These levels are called mandatory pressure levels and are the surface, 850 mb, 700 mb, 500 mb, and 300 mb or 200 mb.

What does the L mean on a weather map?

In cold air the gas molecules slow down, causing low atmospheric pressure. On weather maps, these readings are represented as a blue “H” for high pressure or a red “L” for low pressure.

What does a warm front symbol look like?

A warm front is defined as the transition zone where a warm air mass is replacing a cold air mass. Symbolically, a warm front is represented by a solid line with semicircles pointing towards the colder air and in the direction of movement. On colored weather maps, a warm front is drawn with a solid red line.

What symbols are commonly found on a weather map?

These often include temperature, dew point (a measure of humidity), wind speed, wind direction, present weather, barometric pressure and pressure tendency (is it rising or falling?), cloud cover, and many others.

What does purple mean on a weather map?

Extremely heavy rain

What are the symbols for fronts?

Symbols are used on surface weather maps to indicate the characteristics or type of front.

A stationary front line is indicated by blue triangles on one side of the line alternating with red semi-circles on the opposite side of the line.
A cold front is a front that is moving in the direction of the warmer air.

What is a symbol for a stationary front?

A stationary front is represented by alternating blue and red lines with blue triangles pointing towards the warmer air and red semicircles pointing towards the colder air. A noticeable temperature change and/or shift in wind direction is commonly observed when crossing from one side of a stationary front to the other.

How fast does a weather front move?

Cold fronts generally advance at average speeds of 20 to 25 mph. toward the east — faster in the winter than summer — and are usually oriented along a northeast to southwest line.

What is the edge of a cold or warm front?

With cold fronts and warm fronts, the air mass at the leading edge of the front gives the front its name. In other words, a cold front is right at the leading edge of moving cold air and a warm front marks the leading edge of moving warm air.

Which front moves the fastest?

Cold fronts

What is a warm and cold front?

A cold weather front is defined as the changeover region where a cold air mass is replacing a warmer air mass. Cold weather fronts usually move from northwest to southeast. A warm weather front is defined as the changeover region where a warm air mass is replacing a cold air mass. …
