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:. Lab. Fronts!. Fronts!. What are fronts?. A narrow transition zone, or boundary, between differing synoptic scale air masses whose primary discontinuity is density. Fronts highlight . baroclinic. zones, where temperature advection and atmospheric energy is at work. An . air mass. is a . large . pool of air having similar temperature and moisture . characteristics. . An air mass occupies thousands of square miles of the Earth's surface. Air masses are . created . 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.. 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. The Causes of Weather. Objectives:. Compare and contrast weather and climate. Analyze how imbalances in the heating of the Earth’s surface create weather. Describe how and where air masses form. Meteorology is the study of atmospheric phenomena, from the ancient Greek meteor “high in the air”. . . 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 (. ATMO 1300. Summer II . 2017. Air Mass. A large body of air in which there are similar horizontal temperature and moisture properties.. . Properties largely acquired from underlying surface. Air masses can cover thousands of miles. 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..
