10 Mid-Latitude Cyclones Objectives Aftraompleting these exmies, you should heaNeto: I Explain how weather conditions dffer at various locations around a midlatitude gelone Detect the passage of cold front from meteorological data I Predict the likely weather changes as the odone andits associated fronts pass I Explain the ir on the dymamics of a mid-latitude cyclone Introduction How do mid latitude cyclones form and mature creating a wave (Figure 10 la). Under some con ditions this wave may amplify, allowing warm air and how do these low pressure cells affect the weather? This lab uses idealized and real-world to penetrate poleward and cold air to penetrate mples to illustrate the surface weather patterns equatorward. This penetration can cause a low associated with mid-latitude cydones. It also pressure center to develop along the wave (Figure examines how winds above Earth's surface influ 10 lb). In this stage warm air is fo upwar along the cold and warm fronts and dose to the ence storm processes, development, and move low pressure center. Since cold fronts typically advance faster than warm fronts, the warm air sec toris progressively lifted from the surface, and an The Polar Front Theory We begin by examining the Nonwegian pabussos Pauppdudedfront forms (Figure 10 1c).This marks the most intense stage of the mid latitude theory, which provides a model for mid latitude cyclone, characterized by maximum cloud cover cydone development. In this model, cydones form along a front dividing a warm sub and precipitation, and the steepest pressure gradi stationary tropical air mass from a cold polar air mass. The ent.

Lutgens,Edward u Tratbuck and oerris Tasa 200, oeh Ednon copydghte 2004 by Lutgens, Tarbucks and Tasa Reprinted with permissaan of Pearson Educanon, inc., Upper Saddle River. NUExplanation / Answer
1)The air masses labelled as triangles represent warm air and the those symbolised as semicircles represent cold air
2)The direction of wind movement is roughly parallel to the isobars,so wind moves east from A,south east from B,south south east from C and north west from D.
3)1st coloumn represents station C,2nd coloumn represents station D,3rd coloumn represents station A,4th coloumn represents station B.
