= = = = = __Weather Systems and Hazards__ = == Textbook Reference:Revise KS3 Geography Study Guide: only pages 56-7(for lessons U2C and U3D) == One of the most devastating types of weather comes in the form of hurricanes. These hit particular parts of the Earth in defined seasons. The first 2 lessons will be looking at what happens to a rich country and to a poor one when this happens. The next 2 lessons are about weather systems that occur throughout the world, anticyclones and depressions. These systems bring different types of weather with them. Finally, we look at an alternating pair of weather systems in the South Pacific, El Nino and La Nina, which can have wide ranging effects over many parts of the world.
