Weather Model Discussion:  How To Use Surface Dew-points For Weather Forecasting Purposes
2013-01-29 08:53:47

Surface Dew-points can play a huge role in weather forecasting. The first such role is that it helps determine the amount of moisture in the atmosphere for a given point. If we look at the current dew-point map above from January 28, 2013 we can note several things of interest. First, if we look at where the black circle is around the number 70, we can make note that this air right off the coast of Texas is at a dew point of 70F. The temperature outside must be above 70F, because the...

Weather Education - Air Mass Thunderstorms
2013-01-13 10:30:47

Air mass thunderstorms are found in marine time tropical air. In short they are also known as MT Thunderstorms. Air mass thunderstorms represent what is known as the common three stage thunderstorm development. This means that an air mass thunderstorm goes through the stages of Cumulus which is represented by the updrafts only being present; secondly it moves into the mature stage where it has both updrafts and downdrafts; finally it goes into the dissipating stage where you see only the...
