The standard averaging period is 30 years, but other periods may be used depending on the purpose. Weather: the state of the atmosphere with respect to temperature, rainfall, cloud cover, and wind. Jetstream high velocity windstream that is ~20 km above us, moves around. Jetstream usually separates cold air masses in the north from much warmer air masses in the south. Weather determining clouds are much closer to the ground than the. Climate zones: climate zones are commonly defined using the parameters of temperature and rainfall. What are the controls on global climate? (climate zones) If it wasn"t for photosynthesis, there would be no oxygen for us to use to breath. Happens in the water too ex. ) photoplankton & phytoplankton.
