Desert climate: Large region characterized by hot and arid conditions. One of the five main climates in the principal classification system.

Wetlands in Ireland and the UK typically receive about 1,500 mm of rain, annually.
In the Pantanal, mean annual rainfall is 1100mm , during Southeast Asia, wetlands can receive up to 10,000mm .

It is possible to typically find this type of climate near the equator from 15°N to 15°S latitude.
The Koppen climate classification was developed by Wladimir Koppen more than a century ago.
Because Koppen was a botanist, he heavily ties climate to vegetation.

Distance to the equator is one section of an area’s climate.
Things like the movement of the oceans and Earth’s tilt and rotation also affect how weather patterns move around the globe.

Deciduous trees lose their leaves each fall and remain leafless in the wintertime.
Thus, little photosynthesis occurs during the dormant winter period.
Because of the dormant period, the web primary productivity of temperate forests is significantly less than that of tropical rainforests.
Furthermore, temperate forests show far less diversity of tree species than tropical rainforest biomes.
The tropical wet-and-dry category (start to see the climate graph for Cancún) has a pronounced dry season.

  • The categories were also influenced by a region’s latitude—the imaginary lines used to measure our Earth from north to south from the equator.
  • Despite its name, the temperate climate zone is in fact quite diverse, with variations in temperature, precipitation, and other weather patterns.
  • During its journey through the water cycle, this freshwater absorbs chemicals along with other materials from the atmosphere, and from the sea and land mass over which it travels.
  • Organisms with carbonate skeletons did not appear in great numbers until the Cambrian period, which began about 541 million years ago.
  • The annual precipitation of the Arctic tundra is low (15–25 cm or 6–10 in) with little annual variation in precipitation.
  • Tropical rainforests are located in equatorial regions will be the most biodiverse terrestrial biome.

Many plants have adapted leaf shapes that allow water to drain away quickly to reduce surface moisture that might facilitate the growth of bacteria and fungi.
Savannas are characterized more by their warm climates than by their grasses and scattered trees.

Hot Desert Climates

Herbivores will be the major food source for most predators, however they also depend upon predators to eliminate aging or diseased animals, to maintain the fitness of the herds.

Species biodiversity of this freshwater biome is normally limited due to its isolated and fragmented geography.
Below the canopy are three layers that define the ‘understory’, standing about 9–15m (30–50 ft) shorter compared to the canopy.
The upper section includes shorter mature trees , saplings, and juvenile canopy layer trees awaiting an opening in the canopy, by which to rise.
Finally, there is the bottom cover or herbaceous layer — the layer with variety .
Temperate deciduous forests routinely have a 4-layer structure.

What Exactly Are Köppen’s Five Main Climate Types?

In the tropics, wetlands are much warmer for a larger portion of the entire year.
In the Pantanal, for instance, temperatures during the year range between 20–33°C (68–91°F).
In Western Siberia, average January temperatures range from minus 15 °C (5 °F) in the southwest to minus 30 °C (minus 22 °F) in the northwest.
Average July temperatures, range between 20 °C (68 °F) in the south to 20 °C (68 °F) in the north.
In the Sonoran Desert of the southwestern United States and northern Mexico, skies are clear.
The typical weather is extremely hot summer days and cold winter nights.
Although annual rainfall is significantly less than 25

  • They look like tiny tornadoes, however they start on the ground instead of in the sky.
  • Through the summer these areas are influenced by stable subtropical highs, that give them dry, the sunshine.
  • Some scientists believe that Earth will enter another ice age in just a few thousand years.
  • on the seasonality of these precipitation.

The bleak coastal Magdalena Plain’s only conspicuous endemic plant is the weird creeping devil cactus , but inland the rocky slopes are rich and dense with trees, succulent shrubs, and cacti .
Autumn (October & November)Warm temperatures; low humidity; little rain; few species in flower, however the growing season for winter annuals begins if there is enough rain. [newline]Late summer and autumn occasionally receive heavy rains from the remains of Pacific hurricanes .
Some ecologists broaden the idea of riparian communities to add the banks of dry washes in deserts.
A wash in the low Colorado River Valley with its woodland of palo verdes (Cercidium spp.), ironwoods , and desert willows is actually distinct from the encompassing creosote bush flats.

With less skin tightening and in the atmosphere, temperatures cooled worldwide.
By the late Carboniferous , North America—which was area of the continent of Laurussia—had collided with Gondwana.
This collision was section of the formation of Pangaea, a supercontinent comprised of nearly all the landmass on the planet.
Global temperatures again declined, an glaciation continued close to the South Pole.
This ice age lasted well into the Permian, ending about 260 million years back.
The finish of the Permian was a time of dry, warming conditions and lower sea levels.
