Explanation:

 Extratropical cyclones, sometimes called mid-latitude cyclones or wave cyclones generally develop beyond the tropics and are associated with frontogenesis. The passage of the front causes abrupt changes in the weather conditions over the area in the middle and high latitudes. • Extratropical cyclones form along the polar front. Initially, the front is stationary. In the northern hemisphere, warm air blows from the south, and cold air from the north of the front. o When the pressure drops along the front, the warm air moves northwards and the cold air moves towards, the south setting in motion an anticlockwise cyclonic circulation. The cyclonic circulation leads to a well-developed extratropical cyclone, with a warm front and a cold front.

• The processes of wind circulation both at the surface and aloft are closely interlinked. The extratropical cyclone differs from the tropical cyclone in a number of ways. The extra tropical cyclones have a clear frontal system which is not present in the tropical cyclones. • The extratropical cyclones cover a larger area and can originate over the land and sea. Whereas tropical cyclones originate only over the seas and on reaching the land they dissipate. Hence statement 1 is not correct. • The extratropical cyclone affects a much larger area as compared to the tropical cyclone. The wind velocity in a tropical cyclone is much higher and it is more destructive. Hence statement 2 is correct. • The extra tropical cyclones move from west to east but tropical cyclones, move from east to west. Hence statement 3 is correct.
