Wind flow direction is from equator to poles is correct. As equator has higher temperature and the air which evolves near the equator become warm due to its higher temperature. When it is nearer to earth surface it flows away towards the poles. The warm air present just above the equator flows towards the north pole Wherase the warm air present just below the equator flows towards the south pole. When this air gets cool it again flows towards the equator. Hence, this process keeps repeat. Therefore, this process is known as convection in earth's atmosphere. A basic figure is shown below for better understanding of this procedure :-

A glider aircraft initially traveling due west at 84.0 km/h encounters a sudden gust of wind at 34.5 km/h directed toward the northeast. What are the speed and direction of the glider relative to the ground during the wind gust? (The velocity of the glider with respect to the ground is the velocity of the gilder with respect to the wind plus the velocity of the wind with respect to the ground.)
