On station models, the speed of the wind is expressed as a series of notches, called “wind barbs” on the clockwise side of the line representing wind direction.
What do station models represent?
In meteorology, station models are symbolic illustrations showing the weather occurring at a given reporting station. Meteorologists created the station model to fit a number of weather elements into a small space on weather maps.
How do you read air pressure in a weather station model?
Air pressure on a station model only contains the last 3 digits of the air pressure. A pressure of 995. 0 mb is written as 950 on the station model. A pressure of 1032 is written as 320 on the station model.
How do you read wind symbols?
The staff part of a wind barb shows wind direction. The dot end of the staff is where the wind is blowing to, while the top of the staff shows the direction from which the wind is coming. The top row of wind barbs in the figure to the right all indicate a north wind.
How do you read a pressure trend?
The pressure trend has two components, a number and symbol, to indicate how much (in tenths of millibars) in the past 3 hours and the trend in the change of the pressure during the same period. In above case, the pressure was falling after steady or slightly rising and becoming 3 mb LOWER than it was three hours ago.
What does high pressure mean?
typically. High pressure often means dry weather with sunshine. Low pressure often means clouds and precipitation. High pressure is associated with sinking air. Air pressure is higher because it is pushing DOWN on the ground.
