PPT-Weather Forecasting Air Masses and Fronts

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 AOS 101 Weather and Climate. Lisha. M. . Roubert. University of Wisconsin-Madison. Department of Atmospheric & Oceanic Sciences. Fronts: The Boundaries between Air Masses. A front is defined as the transition zone between two air masses of different density. . 8. th. Grade. Definition. Weather front – The area where two air masses meet and do not mix.. Front and Weather. Different types of fronts produce different patterns of weather. . There are four types of weather fronts:. 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 . Forecasting Weather. Now that Meteorologists understand the factors that affect weather they must put all of this together to create . weather maps. and to determine . weather patterns. .. Together weather maps and weather patterns are very helpful in . What’s the difference?. Air Mass. An . air mass . is a large volume of air with the same temperature and moisture content.. As an . air mass . forms, it takes on the characteristics of the area over which it develops.. 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.. The way they circulate . (clockwise or counterclockwise). . 1. An air mass is a wide-spread section of the troposphere with uniform . temperature . and . humidity . (moisture). 2. The source region is the geographic location the air mass developed over. . If air settles over one location for a long time, it develops the characteristic temperature and moisture of the area.. Connecting the Weather. Air Masses. Fronts. Jet Stream. Quiz. Midweek Seminars. Meteorology – Jet Streams Fronts and Air Masses. Air Masses. A mass . of air takes on Temperature and Moisture from where the . is the study of atmospheric phenomena.. The Causes of Weather. Weather and Climate. Weather. is the current state of the atmosphere, including short-term variations that affect our lives.. The Causes of Weather. . Movements of Air Masses and Fronts are vital to our . understanding. and . prediction. of Weather Systems. . Weather Forecasting. requires that we understand. :. Cyclones (. L. =Lows) and Anticyclones (. Lisha. M. . Roubert. University of Wisconsin-Madison. Department of Atmospheric & Oceanic Sciences. Fronts: The Boundaries between Air Masses. A front is defined as the transition zone between two air masses of different density. . Air masses. A body of air with similar characteristics throughout. Humidity. . and . temperature. are the two main characteristics used to classify air masses.. The “first name” of an air mass describes the humidity of the air mass.. air masses.. . An . Air Mass. is an immense body of air, some 1600+ km (~1000mi) across and 1-3 km (~.6 to 1.9mi) thick, with relatively homogeneous physical properties (density, T. . and moisture) at a given altitude..
