Document Summary
During strong winds, air will mix and vertical gradients of temperature will be smaller. In 1817, natural scientist alexander von humboldt drew the rst isothermal lines. he suggested the idea of comparing the climate conditions of various countries. Energy in the process of being transferred from one object to another because of the temperature di erence between them. In the atmosphere, heat is transferred by conduction, convection, advection, and radiation. Convection: soaring birds, like hawks and falcons, are highly skilled at nding thermals. The transport of substance by motion: for example, warm air that is created over deserts can be transported by wind to cooler areas. Materials di er in their ability to heat up, namely, to change their temperature when heat is added to them. This property of materials is referred to as heat capacity (their capacity to heat up). Heat capacity the ratio of heat energy absorbed by a substance to its corresponding temperature rise.
