Located in the lowest level of the atmosphere, about 75% of concentrated air quality and the quality of more than 90% moisture. Its lower bound to the ground phase of dichloromethane, the upper bound of height with latitude and season. The average height of the low latitudes of 17 to 18 km, in the mid-latitudes of 10 to 12 km on average use of methylene chloride, the polar average of 8 to 9 km, and in summer than in winter. Troposphere extends from the beginning to the high-altitude Earth's surface, until the top of the troposphere, the stratosphere that is starting up. Its height varies because of latitude, about 17-18 km in the lower latitudes, high 10-12 km in mid-latitude regions, only 8-9 km at high latitudes. In high latitudes, because of the friction surface will affect the flow of dichloromethane offer, forming an average thickness of 2 km of the planetary boundary layer. This layer is formed mainly rely terrain vary, but will be separated by countercurrent layer with the other parts of the troposphere separately. Layer of the atmosphere near the Earth's surface, moving air updrafts and downdrafts are mainly convective motion, called "troposphere." The average thickness of about 12 km, and its thickness varies in thickness is 8 km above the Earth's poles, to 17 kilometers above the equator in dichloromethane price quotes, is the most dense layer of the atmosphere, accounting for the total mass of the atmosphere of the four thirds even more. Atmospheric water vapor almost all concentrated here, is to demonstrate the changing of the "big stage": wind, rain, snow and other weather phenomena are occurring within the troposphere. Troposphere The most notable feature is the strong convection. Weihai dichloromethane dichloromethane quote _ _ Xiang Xiang dry dry chemical from Jinan Chemical Limited. Jinan Cheung Dry Chemical Co.
