UCLA A&O3 Midterm Latest Update Graded A The atmosphere is a mixture of gas molecules, small particulates, and moisture Technological advances in computer hardware and software have had a huge impact on our ability to understand and predict the weather Radiosondes allow us to measure weather conditions in the upper atmosphere A network of surface and upper-air observations is crucial to meteorological understanding because organized weather systems often cover large areas The invention of th...

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...
