Weather Maps--The Surface Station Model and Surface Weather Maps

Ø  The Surface Station Model and Surface Weather Maps

̶        Temperature, pressure, moisture, and wind measurements are reported hourly at the surface (most are usually made 2 meters above the ground)

̶        Station Model:

·         Isobars: Lines of constant pressure

·         Pressure Gradient: Where pressure changes over distance

·         Temperature Gradient: rapid change in temperature with distance

·         Isotherms: Lines of constant temperature
