Weather Maps Storms Weather Maps Weather Stations Show the following data in a concise way cloud cover wind direction wind speed temperature precipitation . Fronts • Weather observations are plotted on a station model (circle ) • Air temperature (T) is plotted in the upper left • Dew Point temperature (T D ) is plotted in the lower Great Flood of 1937. 70% of Louisville was submerged. 3.3 billion in damages. Crest - 85.4 ft. (Flood Stage – 55 ft.). 15 inches of rain in 12 days. Chapter 1: Monitoring the Weather (Basics). One of the Deepest Extratropical Cyclones Ever Recorded. Front: a boundary between 2 air masses. Warm air and cold air do not mix well.. Changes in weather occur along fronts.. 4 Types of fronts:. Cold Front. Warm front. Stationary front. Occluded front. 1. Cold Front. the. Weather. Sun = Energy driving weather. Equator = warm; Poles = cold .  . why. ?. Daytime: air over land warmer than over water; reverse at night. .  . why. ?. Convection currents . We will go over how to upload your file into canvas together.. Wanted Poster Requirements. You are making two posters.. The name and a picture of the Pressure Systems..
