Weather most often results from climate differences from one planet to another. On big scales, climate differences occur mainly as areas closer to Earth's equator get more energy per unit area from the Sun than do regions nearer to Earth's poles. On neighboring scales, temperature differences can happen because different surfaces have opposed physical characteristics for instance reflectivity, roughness, or moisture content.
Surface temperature differences in roll cause pressure differences. A hot surface heats the air over it and the air expands, lowering the air force. The resulting parallel pressure exit up accelerates the air from high to low down of pressure, creating wind, and Earth's rotation then causes curving of the pour via the Coriolis Effect. The bodily powerful temperature contrast among polar and tropical air gives rise to the jet flow. The majority weather systems in the mid-latitudes are caused by instabilities of the jet stream of the flow. The Weather systems in the tropics are arising by various processes, like monsoons shower systems.
