Question
12. Each of the four illustrations to the right represents the wind flow pattern around an area of surface high pressure or surface low pressure in either the Northern Hemisphere or the Southern Hemisphere. a. For each, indicate whether the surface pressure system is low or high and whether the system is located in the Northern Hemisphere or Southern Hemisphere. 13. Answer the following questions using the illustration to the right (a surface weather map in the Northern Hemisphere) 1012 076 1028 a) What is pressure at point P? b) At point P the wind would most likely be blowing from which direction? c) Would the wind at point S most likely be blowing from the southeast, southwest, northeast, or northwest? d) Would you expect stronger winds at point P or point Q? Explain. e) Should the air above the H be rising or sinking?Explanation / Answer
Answer 12: The wind moves in accordance with the earth’s rotation around its axis. The Northern hemisphere deflects wind to the right (clockwise) while the Southern hemisphere deflects wind to the left (anticlockwise) and works with the movement of air being from High Pressure points to Low pressure points. You have to understand that low pressure and high pressure points coexist at the same time and hence in the Northern Hemisphere, high pressure wind moves to low pressure in a smooth circular manner.
