GEOG 155 Lecture Notes - Lecture 3: Climatology, Thermosphere, Particulates
Document Summary
Five spheres make up the thermal atmosphere (measuring the temperature) Layers aren"t just separated by their temperature, scientists. Special layers have different categories for different measurements. First international meeting addressing the ozone layer hole. Air pressure: the force exerted as gravity pulls the atmosphere towards the. Analogous to the weight of the air. As elevation increases, air pressure decreases & vice versa. 90% of atmosphere is in lowest 16 km. 1113 mb is the average atmospheric pressure at sea level or 29. 92. Often measured in milibars (mb) inches of mercury. : line connecting points of equal atmospheric pressure. Weather: the day to day occurrences of the atmosphere. Climate: the long term average of weather in a location. Ex: getting ready for a trip to jamaica in june , using the average to pack cool/summer clothes. Poles are cold b/c they are far away from rays of the sun. Water heats and cools more slowly than land.
