Weather is a set of all the phenomena occurring in a given atmosphere at a given time.Merriam-Webster Dictionary. Retrieved on 2008-06-27. Most weather phenomena occurs in the troposphere.Glossary of Meteorology. Retrieved on 2008-06-27."trop">Glossary of Meteorology. Retrieved on 2008-06-27. Weather refers, generally, to day-to-day temperature and precipitation activity, whereas climate is the term for the average atmospheric conditions over longer periods of time. When used without qualification, "weather" is understood to be the weather of Earth.
Weather occurs due to density (temperature and moisture) differences between one place and another. These differences can occur due to the sun angle at any particular spot, which varies by latitude from the tropics. The strong temperature contrast between polar and tropical air gives rise to the jet stream. Weather systems in the mid-latitudes, such as extratropical cyclones, are caused by instabilities of the jet stream flow. Because the Earths axis is tilted relative to its orbital plane, sunlight is incident at different angles at different times of the year. On Earths surface, temperatures usually range ±40 °C (100 °F to −40 °F) annually. Over thousands of years, changes in Earths orbit affect the amount and distribution of solar energy received by the Earth and influence long-term climate
Surface temperature differences in turn cause pressure differences. Higher altitudes are cooler than lower altitudes due to differences in compressional heating. Weather forecasting is the application of science and technology to predict the state of the atmosphere for a future time and a given location. The atmosphere is a chaotic system, so small changes to one part of the system can grow to have large effects on the system as a whole. Human attempts to control the weather have occurred throughout human history, and there is evidence that human activity such as agriculture and i read more at » http://en.wikipedia.org/wiki/Weather
