NOTE: We've guessed that you're not using a client that supports colored tables and have tried to compensate. Low graphics mode looks much better on clients that do... we recommend switching to Netscape 3.0 or Microsoft Internet Explorer.
Cold Advection
cold air moves into a warmer region

Cold advection is the process in which the wind blows from a region of cold air to a region of warmer air. The following animation depicts a very simple example of cold advection. The horizontal lines are isotherms in degrees Fahrenheit and the arrows represent wind vectors. Winds are blowing from a region of cold air to a region of warmer air, which results in cooling of the warmer region. As the cold advection persists, temperatures in the warmer region will begin to decrease as the colder air moves into the region of warmer air.
