Wind speed and direction |
Learning how to chart weather conditions and
interpreting them is important. In this exercise you are asked to look
at several internet sites to interpret the weather. First, we need to
define the different weather elements. The elements that make up the
weather include the type of clouds in the sky, the temperature of the
air, the amount of moisture or humidity in the air, and the speed
and direction that the wind is blowing.
Symbols on weather charts help the meteorologist
chart and predict the weather easily. If you make a chart of the
pressure measured in millibars of mercury, you can get a sense of the
direction of weather. Pressure is influenced by humidity and
temperature.
Charting pressure helps to predict where the
weather pattern is going. Atmospheric pressure moves weather systems.
Cold air is more dense than warm air causing what is called high
pressure.
