Climate, from the Greek word klima (κλίμα), is the over all weather pattern for an extended period for any defined geographical location which may be over any size of area up to and including the entire Earth. Climate differs from weather in that on a particular day in a desert, for example, there may be rainy weather, but for most days for many years there is little or no rain—rainy weather for a day in a desert climate for many years. Two places, in other words, like Bombay, India and Vladivostock may both have similar weather for a brief time, such as a cloudless, sunny day, but their climate is extremely different. Put another way, weather may change from day to day or hour to hour, whilst climate is the average weather pattern for many years. Commonly the weather patterns that define a climate are averaged for a period of 30 years.
Climate is also different from season. A season [1] is usually a period of time of months, in which the weather can change drastically. Typhoon season in Asia is very windy and rainy. In some places it may rain a great deal for many months. The reminder of the year, the weather can be virtually without rain.
Climate variables include, precipitation (frost, fog, rain hail storms, snow), humidity (water vapour in the air), wind, amount of sunlight, temperature and other measures of weather.
Microclimate
Microclimates are distinctive, small-scale climates that are specific defined areas, such as valley’s or regions on either side of a geological feature such as a mountain range that alters the precipitation, wind, sunlight, humidity to such an extent as to make the local climatically different from the surrounding areas. A heavily wooded park within in an industrialized urban setting will differ climatically from the surrounding buildings and paved areas, a valley branching off a large region of desertification may offer significant climatic variables. [4]
Over time, plants and animals may adapt to these different microclimates to such an extent that they may thrive in a small defined ara with a specific microclimate and yet if they are moved a short distance they will languish and show reduced growth and health, possibly even reduced abilty to multiply.
Microclimate may also refer to artificially controlled environments such as botanical gardens, archives or museums where specific requirements are not naturally available.[5]
