PPT-Meteorology The study of the changes in temperature, air pressure, moisture, and wind

Tuesday September 20 2011 Objectives 1 Explain the composition structure and properties of Earths Atmosphere 2 Explain the difference between Earths Early Atmosphere and the current Atmosphere. Three real forces . (gravity, pressure gradient, and friction) push the air around. Two apparent forces . due to rotation (Coriolis and centrifugal). Large-scale flow is dominated by gravity/pressure and Coriolis … . 003: Lab 4. Chapter 4: 14ab, 15c. Chapter 5: 4abc, 10ab, 18. Chapter 6: 2ab, 7ab, 9acd. Chapter 7: 9ab. 4.14a,b. pg. 163.

What is Wind. ?. Wind is air moving across the surface of the Earth. It can move horizontally or parallel to the ground.. Friday . 09. /. 26. /2014. Continue . Review Material. Geopotential.

Motivation. Moisture is an important factor in cyclogenesis. Moisture is a necessary ingredient in extreme precipitation events. Neiman and Shapiro (1993). Motivation. Latent heating modifies the pressure field around cyclones, affecting the track and intensity of the surface cyclone. What is air pressure?. Air Pressure: the force exerted by the weight of the air above it. Why does the weight of the air not crush you?. The pressure is exerted in all directions, not just down. (Ruler and newspaper demonstration). Will air circulate Clockwise or Counterclockwise around each of these pressure centers?. H. L. Cyclonic and anticyclonic winds in the Northern Hemisphere. Cyclones and anticyclones . Cyclone. A center of . 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”. . It is caused by:. 1.Differences in . temperature. .. 2.Differences in . pressure. .. WIND.

For 80%+ of the atmosphere outside of the inner tropics, the geostrophic relationship is quite good.. Rolf Reichle. 1. , Gabrielle DeLannoy. 1,2. , and . Wade Crow. 3. 1.
