San Antonio's location is marked with an asterisk. We will analyze this map to get a handle on the weather in San Antonio during that time. a. To begin, draw isotherms at all multiples-of-ten. b. Undoubtedly, you have heard the term "front" used by meteorologists, and you may have noticed that fronts are often associated with active weather. In general, a front is a boundary between huge masses of air of contrasting temperature. Thus, a front is a zone of relatively large temperature gradient—on a weather map, such

Unformatted text preview: a zone would be identified by a tight packing of isotherms. To isolate that zone on the 00Z map, lightly shade in all areas where temperatures are 60F or higher, representing relatively mild air. Then, lightly shade in areas where temperatures are 30F or lower, representing relatively cold air (note that these particular values are specific to this case). What's left unshaded is the corridor of large tempera-ture gradient, and the front is found in this zone. C. Use the wind portion of the station models to make a conclusion about the behavior of the wind (specifi-cally, its direction) as you cross from one side of a front to the other....
