Grasslands All living things are closely related to their environment. Any change in one part of an environment, like an increase or decrease of a species of animal or plant, causes a ripple effect of change in through other parts of the environment.
Definition[ edit ] Climate from Ancient Greek klima, meaning inclination is commonly defined as the weather averaged over a long period. Climate also includes statistics other than the average, such as the magnitudes of day-to-day or year-to-year variations.
Although Köppen’s classification did not consider the uniqueness of highland climate regions, the highland climate category, or H climate, is sometimes added to climate classification systems to account for elevations above 1, metres (about 4, feet). Due to its link with the plant life of a region, the system is useful in predicting future changes in plant life within a region. The Köppen climate classification system has been further modified, within the Trewartha climate classification system in the middle s (revised in ).

Climate in a narrow sense is usually defined as the "average weather," or more rigorously, as the statistical description in terms of the mean and variability of relevant quantities over a period ranging from months to thousands or millions of years.
These quantities are most often surface variables such as temperature, precipitation, and wind. Climate in a wider sense is the state, including a statistical description, of the climate system. A Normal is defined as the arithmetic average of a climate element e. A 30 year period is used, as it is long enough to filter out any interannual variation or anomalies, but also short enough to be able to show longer climatic trends.
At its Wiesbaden meeting the technical commission designated the thirty-year period from to as the reference time frame for climatological standard normals. In the WMO agreed to update climate normals, and these were subsequently completed on the basis of climate data from 1 January to 31 December These change only over periods of millions of years due to processes such as plate tectonics.
Other climate determinants are more dynamic: The density and type of vegetation coverage affects solar heat absorption,  water retention, and rainfall on a regional level. Alterations in the quantity of atmospheric greenhouse gases determines the amount of solar energy retained by the planet, leading to global warming or global cooling.
The variables which determine climate are numerous and the interactions complex, but there is general agreement that the broad outlines are understood, at least insofar as the determinants of historical climate change are concerned.
Originally, climes were defined in Ancient Greece to describe the weather depending upon a location's latitude. Modern climate classification methods can be broadly divided into genetic methods, which focus on the causes of climate, and empiric methods, which focus on the effects of climate.
Examples of genetic classification include methods based on the relative frequency of different air mass types or locations within synoptic weather disturbances. A common shortcoming of these classification schemes is that they produce distinct boundaries between the zones they define, rather than the gradual transition of climate properties more common in nature.
Bergeron and Spatial Synoptic[ edit ] Main article: Air mass The simplest classification is that involving air masses. The Bergeron classification is the most widely accepted form of air mass classification.
The first letter describes its moisture properties, with c used for continental air masses dry and m for maritime air masses moist. The second letter describes the thermal characteristic of its source region: T for tropicalP for polarA for Arctic or Antarctic, M for monsoonE for equatorialand S for superior air dry air formed by significant downward motion in the atmosphere.
The third letter is used to designate the stability of the atmosphere. If the air mass is colder than the ground below it, it is labeled k. If the air mass is warmer than the ground below it, it is labeled w.
There are six categories within the SSC scheme: Dry Polar similar to continental polarDry Moderate similar to maritime superiorDry Tropical similar to continental tropicalMoist Polar similar to maritime polarMoist Moderate a hybrid between maritime polar and maritime tropicaland Moist Tropical similar to maritime tropical, maritime monsoon, or maritime equatorial.

Most summer rainfall occurs during thunderstorms and from occasional tropical cyclones. The climate is characterized by hot, dry summers and cool, wet winters. Ice caps form because high- latitude regions receive less energy as solar radiation from the sun than equatorial regions, resulting in lower surface temperatures.
Many deserts are formed by rain shadowsas mountains block the path of moisture and precipitation to the desert.
