climate is the weather of a region

what is climate?how does it change frequently?

Climate is the pattern of variation in temperature, humidity, atmospheric pressure,wind, precipitation ,atmospheric particle count and other meteorological variables in a given region over long periods. Climate can be contrasted to weather, which is the present condition of these variables over shorter periods.

Climate change is the variation in global or regional climates over time. It reflects changes in the variability or average state of the atmosphere over time scales ranging from decades to millions of years. These changes can be caused by processes internal to the Earth, external forces (e.g. variations in sunlight intensity) or, more recently, human activities.

In recent usage, especially in the context of environmental policy, the term "climate change" often refers only to changes in modern climate, including the rise in average surface temperature known as global warming.


types of climates

Rain forests are characterized by high rainfall, with definitions setting minimum normal annual rainfall between 1,750 mm(69 in) and 2,000 mm (79 in). Mean monthly temperatures exceed 18 °C (64 °F) during all months of the year.

A monsoon is a seasonal prevailing wind which lasts for several months, ushering in a region's rainy season. Regions within North America,South America,Sub-Saharan Africa, Australia and East Asia are monsoon regimes.

A tropical savanna is a grassland located in semiarid to semi-humid climate regions of subtropical and tropical latitudes, with average temperatures remain at or above 18 °C (64 °F) year round and rainfall between 750 mm (30 in) and 1,270 mm (50 in) a year. They are widespread on Africa and are found in India the northern parts of South America, Malaysia and Australia.

The humid subtropical climate zone where winter rainfall (and sometimes snowfall) is associated with large storms that the westerlies steer from west to east. Most summer rainfall occurs during thunderstorms and from occasional tropical cyclones.] Humid subtropical climates lie on the east side continents, roughly between latitudes 20° and 40° degrees away from the equator.

What's the Difference Between Weather and Climate?

Weather reflects short term conditions of the atmosphere while climate is the average daily weather for an extended period of time for a certain location.We hear about weather and climate all of the time. Most of us check the local weather forecast to plan our days. And climate change is certainly a “hot” topic in the news. There is, however, still a lot of confusion over the difference between the two.

Think about it this way: Climate is what you expect, weather is what you get.

Weather is what you see outside on any particular day. So, for example, it may be 75 degrees and sunny or it could be 20 degrees with heavy snow. That’s the weather.

Climate is the average of that weather. For example, you can expect snow in the Northeast in January or for it to be hot and humid in the Southeast in July. This is climate. The climate record also includes extreme values such as record high temperatures or record amounts of rainfall. If you’ve ever heard your local weather person say “today we hit a record high for this day,” she is talking about climate records.
