GEOG 1900 Exam #2 Questions and Answers 100%Solved What instruments are used to measure wind? Anemometer, Radiosondes (weather balloons), Tethersonde, Doppler Radar, Wind Vane Identify the general characteristics associated with winds and pressure gradients Pressure Gradient: Drives winds from high to low pressure. Coriolis Effect: Earth's rotation deflects wind direction. Isobars: Map lines indicate wind strength. High/Low Pressure: High = clear weather, descending air; Low = stor...

How can you identify a region of strong pressure gradient on a weather map? What does strong pressure gradient imply about the strength of wind? Answers- When isobars are closer then there is a higher pressure gradient. That means the winds are stronger where pressure gradient is highest What are the forces that act on the air to make wind blow? Answers- - The pressure gradient is the source for all wind. - Air moves from high pressure to low pressure In the Northern Hemisphere, why do w...
