Global Atmosphere Circulation continued-The 3 cell model is a simplification- the Earth’s surface has land and water-The ICTZ and the thermal equator are not straight lines!-The pressure and wind bands are patchy because the 3 cell model leaves out land/water differences.-There are weak thermal lows in the Southern Hemisphere because the land areas are relatively small. -Air rising means low pressure.-Land/water heating differences produce local winds.-Monsoon weather is driven by summertime development of thermal lows. II. Clouds-Indicate the condensation of water vapor from the atmosphere. If enough condensation occurs, precipitation happens.-For clouds to form, air must be cooled and lifted. i. How air is lifed-Convectional uplif: stronger over cities-Convergent uplif: Once the circulation gets going, it’s a convergent uplift. The air has to go up.These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.-Orographic uplif: Happens with the physical interaction of wind and a mountain. The wind can’t go around or through the mountain, so it has to go up. -Frontal uplif: What happens when two air masses collide- one must go up.ii. How uplif makes clouds and precipitation-For water to change, heat energy must be converted or released.-Clouds are made of tiny droplets of liquid water.III. Humidity-Helps the atmosphere absorb and store heat.1.Absolute humidity: The water vapor content of air. There are different measures of absolute humidity. -Specific humidity: The mass of water vapor per mass of air.-Saturation specific humidity: The amount of specific humidity for an air parcel of a given temperature.2. Relative humidity: the amount of water vapor relative to the maximum amount a parcel could hold at a given
