ISP 203B Exam 3 2024 update

ISP 203B Exam 3 If a humid air mass has 100% relative humidity and is 20°C at sea level, what would the temperature of this same air package be if it were pushed over a 2000- m-high mountain range before returning again to sea level? - ANS ️️ 10 degree celsius, b/c there is a 5 degree celsius decrease (idk if this is right) Explain the orographic effect on weather. - ANS ️️ As warm, moist air rises over a mountain, it expands and cools, forming clouds and rain. Descending on the other side, the air contracts, warms, and dries out An area of low atmospheric pressure is characterized by what kind of weather? - ANS ️️ Relatively warm, humid air rises to create low atmosphericpressure areas. Why do the oceans circulate clockwise in the northern hemisphere? - ANS ️️ The Coriolis Effect: forced curvature due to Earth's rotation Explain the right-hand rule as it applies to rotation of winds around a high- or low- pressure center. - ANS ️️ if you point your right thumb in the direction of rising or falling air, your bent fingers point in the direction of air rotation (in the southern hemisphere, use your left hand instead) What is the main distinction between a cold front and a warm front? - ANS ️️ In a cold front, a cold air mass moves more rapidly than an adjacent warm air mass, causing rapid lifting and displacement of the warm air. In a warm front, a warm air mass moves more rapidly than the adjacent cold air mass, and thus it rises over the adjacent cold air mass
