PPT-Weather Fronts

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. 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 and fronts. Review of last lecture. Tropical cyclone structure: 3 major components, rotation direction of inflow and outflow, location of maximum wind and rainfall, 3 feedbacks. Tropical cyclone destruction: 4 reasons? Which side has the most intense destruction? . Dr. . Hooda. . What is an air mass?. A large body of air having nearly uniform conditions of temperature and humidity at any given altitude.. Warm air. forms over . tropical. regions near the equator. . AOS 101 Weather and Climate.

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.. 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 (.

A front is defined as the transition zone between two air masses of different density. . & . the weather they bring. Have you ever wondered why we get certain kinds of weather…cloudy days with lots of rain…sudden storms, then cooler weather…?. All weather happens because of the 4 types of fronts & how they interact:. Fronts occur in the boundary zone between polar and tropical air masses..
