University of Vermont. Avg. The University of Vermont combines faculty-student relationships most commonly found in a small liberal arts college with the resources of a major research institution. The university is home to 10,371 undergraduates, 1,516 graduate students, 460 medical students and 1,299 full- and part-time faculty.
B. Air currents have a direct effect on rainfall. 1. Because Earth rotates on its axis daily and its surface consists of continents and oceans, an overall flow of warm and cold air currents are modified into three large circulation cells in each hemisphere. a) At the equator, the sun heats the air and evaporates water.
Any particles present in the air provide additional sites. Depending on a planes altitude, and the temperature and humidity of the atmosphere, contrails may vary in their thickness, extent and duration. The nature and persistence of jet contrails can be used to predict the weather. A thin, short-lived contrail indicates low-humidity air at high altitude, a sign of fair weather, whereas a thick, long-lasting contrail reflects humid air at high altitudes and can be an early indicator of a storm.
