CLIMATE AND ELEMENTS WEATHER

Weather 

Weather is the day-to-day conditions of a particular place. 

 Most weather phenomena occur in the troposphere, just below the stratosphere.

  Weather is driven by air pressure (temperature and moisture) differences between one place and another.

 These pressure and temperature differences can occur due to the sun angle at any particular spot, which varies by latitude from the tropics. 

 Higher altitudes are cooler than lower altitudes due to differences in compressional heating.

  On Earth, temperatures usually range ±40 °C (100 °F to −40 °F) annually. 

 The coldest air temperature ever recorded on Earth is −89.2 °C (−128.6 °F), at Vostok Station, Antarctica on 21 July 1983.

  The hottest air temperature ever recorded was 57.7 °C (135.9 °F) at 'Aziziya, Libya, on 13 September 1922. 

 However, weather is not limited to planetary bodies.

  A star's corona is constantly being lost to space, creating what is essentially a very thin atmosphere throughout the Solar System.  The movement of mass ejected from the Sun is known as the solar wind. Sunny weather Cold weather Rainy weather Rainy with Thunder Different types of weather  Climate is the average weather in a place over many years or the average weather, usually over a 30-year interval

.  It is measured by assessing the patterns of variation in temperature, humidity, atmospheric pressure, wind, precipitation etc.  It takes hundreds, thousands, even millions of years to change.  Climate is different from weather, in that weather only describes the short-term conditions.  The climate of a location is affected by its latitude, terrain, and altitude, as well as nearby water bodies and their currents.

Elements of Weather and Climate There are several elements that make up the weather and climate of a place. The major of these elements are five:

 • Temperature 

 • pressure 

 • wind

 • humidity 

• precipitation 

Analysis of these elements can provide the basis for forecasting weather and defining its climate. These same elements make also the basis of climatology study, of course, within a longer time scale rather than it does in meteorology.
