These notes summarize all the information required to be learnt by the IEB SAGS document for the mid-latitude cyclone section in climatology geography grade 12. Sign in with your email address. An intense mid-latitude cyclone may have a surface pressure as low as 970 millibars, compared to … QUESTION 1: Urban Climates 5 minutes 10 marks 1. Synoptic Chart Examples. States that cyclones are systems of rotating winds, and how and where mid-latitude cyclones form. Cyclones can be the most intense storms on Earth.A cyclone is a system of winds rotating counterclockwise in the Northern Hemisphere around a low pressure center.The swirling air rises and cools, creating clouds and precipitation. Mid-latitude or frontal cyclones are large traveling atmospheric cyclonic storms up to 2000 kilometers in diameter with centers of low atmospheric pressure. ( … 1 Processes and Spatial Patterns. Additional notes for you to remember on Mid latitude cyclones: Definition Mid altitude cyclones are intense low pressure storms system that develops along the polar front and influences weather in the mid-latitudes (30º - 60ºN/S) Polar front Where westerly and polar easterlies meet at the polar low pressure belt Where? 4 Mid-latitude Cyclones. I acheived 91% for Geography & placed within the top 1% of IEB Geography students. E-mail *. 6 Subtropical anticyclones and the resultant weather over South Africa. Password * Example of Cyclone Development Forced by Upper Flow 12 hours later: • 300 mb upper tropospheric low hasn’t moved too much • … Grade 12. There are two types of cyclones: middle latitude (mid-latitude) cyclones and tropical cyclones. Westerly Winds: Moist warmer winds blowing form the sub-tropical high pressure belt to the sub-polar low pressure belt.

SECTION A: CONTENT NOTES ON MID-LATITUDE CYCLONES TERMINOLOGY / DEFINITIONS (counts up to 25% of Paper 1) Polar Easterly winds: Cold dry winds blowing between the polar high pressure cell and the sub-polar low pressure belt. Connect with social media. In this lesson we examine the origin of mid-latitude cyclones, discuss the conditions necessary for their formation, describe the stages in their development as well as discuss their effect on human activities.
