wind speed | the measure of how fast the air is moving past a measuring point |
humidity | the amount of water vapor in the air |
pressure | the force of air pushing down in all directions |
low pressure systems | atmospheric pressure is lower than normal in this type of system: brings cloud cover and precipitation |
high pressure systems | atmospheric pressure is higher than normal in this type of system; fair weather occurs (with little or no cloud cover/precipitation). |
