What do all these symbols mean? Reading a weather map

Surface observation symbols or weather station symbols , Meteorologists plot weather data collected from hundreds of weather "stations" on a chart or map Meteorologists plot weather data collected from hundreds of weather "stations" on a chart or map

Temperature in degrees Fahrenheit. in degrees Fahrenheit. Temperature is defined as a measure of the average kinetic energy (or speed) of the molecules in the air. Temperature is defined as a measure of the average kinetic energy (or speed) of the molecules in the air ,

Dew Point Dew points indicate the amount moisture in the air. Dew points indicate the amount moisture in the air. When the dew point temperature and air temperature are equal, the air is said to be saturated. When the dew point temperature and air temperature are equal, the air is said to be saturated. Dew point temperature is NEVER GREATER than the air temperature. Dew point temperature is NEVER GREATER than the air temperature ,

Barometric Pressure If reported value greater than 500: Initial 9 is missing. Place it on left, then divide by 10. For example: 827 becomes mb. If reported value greater than 500: Initial 9 is missing. Place it on left, then divide by 10. For example: 827 becomes mb. If reported value less than 500: Initial 10 is missing. Place it on left, then divide by 10. For example (as in above diagram): 027 becomes mb. If reported value less than 500: Initial 10 is missing. Place it on left, then divide by 10. For example (as in above diagram): 027 becomes mb , Pressure reported in millibars (mb)

Wind barb – wind direction Wind barbs point in the direction "from" which the wind is blowing. In the case of the diagram, the orientation of the wind barb indicates winds from the Northeast. Wind barbs point in the direction "from" which the wind is blowing. In the case of the diagram, the orientation of the wind barb indicates winds from the Northeast ,

Wind barb – wind speed 1 Knot = 1.15 Miles Per Hour (MPH) 1 Knot = 1.15 Miles Per Hour (MPH) Each short barb represents 5 knots, each long barb 10 knots. A long barb and a short barb is 15 knots, simply by adding the value of each barb together (10 knots + 5 knots = 15 knots). Each short barb represents 5 knots, each long barb 10 knots. A long barb and a short barb is 15 knots, simply by adding the value of each barb together (10 knots + 5 knots = 15 knots). If only a station circle is plotted, the winds are calm. If only a station circle is plotted, the winds are calm ,
