Document Summary
Jetstreams and temperatures con"t: the jet streams are localized where the temperature gradients are strongest, jetstreams are also commonly used to depict the paths of storms. Storms tend to follow path of jetstream. Forecast of jetstream for later this week: wind is blowing left to right. This implies that it cold above the jetstream and warm bellow. Moisture (water: water vapor, liquid water, ice. Invisible gas composed of individual water molecules: the atmosphere consists of: nitrogen (~ 78. 1% by volume), oxygen (~ 21%), and argon (~ 1%, additionally, water vapor is a highly variable part of the atmosphere (0-6%) Tropics: water vapor represent 4-5% of the air: huge amount available for precipitation. Tropics: 4-5% water vapor: the force per unit area produced by water vapor alone is the vapor pressure, vapor pressure is a measure of the absolute amount of moisture in the air.
