As the snowflakes fall, liquid water freezes onto them forming ice pellets that continue to grow as more and more droplets are accumulated. The word climate is derived from the Greek klima, meaning inclination. The various physical processes such as precipitation, evaporation, infrared radiation, etc interconnect the various components of the climate, its behavior and its properties. Climate is always dynamic, it vary from place to place and from country to country around the world. Mountain ranges and Coastal areas often have a different climate to those of inland.
Climates also vary over time and change very gradually over decades and centuries.
Human activity also greatly influences the climate. Air flows in relation to the earth's surface, generally horizontally and from high pressure to low-pressure area. Winds are described by the direction they blow from - an easterly wind flows from the east, a westerly from the west. Prevailing winds are arranged in a series of belts around the globe. This pattern is the result of the different amounts of solar heating the place gets depending upon the topography.
