Q

Tropical rain forest climate

A

Tropical rain forest climates are constantly moist and warm, convectional thunderstorms, triggered by local heating and trade-wind convergence, peak each day from mid-afternoon to late evening inland and earlier in the day where marine influence is strong along coastlines, huge canopies and sparse vegetation cover near ground

Q

Tropical savanna climates

A

Tropical savanna climates are poleward (toward the north pole or south pole) of the tropical rain forest climates, ITCZ reaches these climate regions for about 6 months or less, summers are wetter than winters

Q

why can the Tropical savanna climates have two temperature maximums during the year

A

because the sun’s direct rays are overhead twice, before and after the summer solstice in each hemisphere as the subsolar point moves between the equator and the tropics

Q

Mesothermal

A

middle temperature, have warm and temperature climates, where true seasonality begins, mild winter

19
Q

the 4 climates of mesothermal

A
  • humid subtropical hot-summer climates
  • Humid subtropical winter-dry climate
  • Marine west coast climates (warm to cool summers)
  • Mediterranean dry-summer climates (dry summers)
20
Q

Humid subtropical hot-summer climates

A

Humid subtropical hot-summer climates either are moist all year or have a pronounced winter-dry period. in fall, winter, and spring, maritime tropical and continental polar air masses interact, generating frontal activity and frequent midlatitude cyclonic storms. These two mechanisms produce year-round precipitation

21
Q

what influences the Humid subtropical hot-summer climates during summer

A

Maritime tropical air masses generated over warm waters off eastern coasts

22
Q

Humid subtropical winter-dry climates

A

Humid subtropical winter-dry climates are related to the winter-dry, seasonal pulse of the monsoons. The extend poleward from tropical savanna climates and have a summer month that receives 10 times more precipitation than their driest winter month, flooding, thunderstorms, and tornadoes can happen

23
Q

Marine west coast climates

A

featuring mild winters and cool summers, maritime polar air masses, cool, moist, unstable, dominate marine west coast climates, marine west coast climate are unusually mild for their latitude

24
Q

The mediterranean dry-summer climate

A

designation specifies that at least 70% of annual precipitation occurs during the winter months. This shifting of stable, warm to hot, dry air over an area in summer and away from that area in winter created a pronounced dry-summer and wet-winter pattern

25
Q

Microthermal

A

means cool temperate to cold, humid micro thermal climates have a winter season with some summer warmth, poleward of the mesothermal climates

26
Q

the 3 climates of microthermal

A
  • Humid Continental Hot-Summer Climates
  • Humid Continental Mild-Summer Climates
  • Subarctic Climates
27
Q

Humid Continental Hot-Summer Climates

A

Humid continental hot-summer climates have the warmest summer temperatures of the microthermal category, have precipitation which may be consistent throughout the year or have a distinct winter-dry period

28
Q

Humid Continental Mild-Summer Climates

A

Humid continental mild-summer climates are slightly cooler, and located farther toward the poles, mild-summer climate, frost-free periods range from fewer than 90 days in the northern portions of these regions to as many as 225 days in the southern parts. Less precipitation, but heavier snowfall which its melting is important to soil-moisture recharge

29
Q

Subarctic Climates

A

Subarctic climates have very cold winter and cool summers, covered by the so-called snow forests of fir, spruce, larch, and birch are the boreal forests of canada and the alga of russia,

30
Q

Permafrost

A

precipitation and potential evapotranspiration both are low, so soils are generally moist and either partially or totally frozen beneath the surface

31
Q

Polar and Highland Climates

A

Have no true summer, daylength increases in summer until daylight becomes continuous, yet average monthly temperatures never rise above 10°C. These temperature conditions do not allow tree growth, low sun altitude even during the long summer days, extremes of daylight between winter and summer, extremely low humidity, high surface albedo impacts

  • tundra
  • ice-cap and ice-sheet
  • Polar marine
32
Q

Tundra Climates

A

Tundra climates have limited plant growth because of cold temperatures, land is under some snow cover for 8-10 months, with the warmest month above 0°C, yet never warming above 10°C, occur only in the northern hemisphere, except for elevated mountain locations in the southern hemisphere,

33
Q

Ice-Cap and Ice-Sheet Climates

A

An ice sheet is a continuous layer of ice covering an extensive continental region, an ice cap is smaller in extent, dry, frigid air masses, receive less than 8 cm of precipitation a year

34
Q

Polar Marine Climates

A

Polar marine climates are more moderate than other polar climates in winter, with no month below -7°C, yet overall they are not as warm as tundra climates. Because of marine influences, annual temperature ranges are low. Average precipitation is 150 cm, and it can snow during any month

35
Q

Dry Climates (permanent moisture deficits)

A

These dry regions occupy more than 35% of Earth’s land area and are by far the most extensive climate over land. Water demand exceeds the precipitation water supply throughout, creating permanent water deficits

  • arid climates; tropical, subtropical hot desert, and midlatitude cold desert regimes
  • Semiarid climates; tropical, subtropical hot steppe, and midlatitude cold steppe regimes
36
Q

Characteristics of Dry Climates

A

Deserts have greater moisture deficits than do steppes, between 15° and 30° latitude in the Northern and Southern Hemispheres

37
Q

the 4 climates of dry climates

A
  • Tropical, Subtropical Hot Desert Climates
  • Midlatitude Cold Desert Climates
  • Tropical, Subtropical Hot Steppe Climates
  • Midlatitude Cold Steppe Climates
38
Q

Steppe

A

a regional term referring to the vast semiarid grassland biome of Eastern Europe and Asia; the equivalent biome in North America is short-grass prairie, and in Africa, it is the savanna. Steppe in a climatic context is considered too dry to support forest, but too moist to be a desert

39
Q

Tropical, Subtropical Hot Desert Climates

A

Tropical, subtropical hot desert climates are Earth’s true tropical and subtropical deserts and feature annual average temperatures above 18°C. Rainfall is from local summer convectional showers. Some regions receive almost no rainfall, whereas others may receive up to 35 cm of precipitation a year

40
Q

Midlatitude Cold Desert Climates

A

Lower temperature and lower moisture - demand criteria, rainfall must be low - in the realm of 15 cm - for a station to qualify as a midlatitude cold desert climate

41
Q

Tropical, Subtropical Hot Steppe Climates

A

Tropical, subtropical hot steppe climates generally exist around the periphery of hot deserts, where shifting subtropical high-pressure cells create a distinct summer-dry and winter-wet pattern. Average annual precipitation in these climates is usually below 60 cm

42
Q

Midlatitude Cold Steppe Climates

A

The midlatitude cold steppe climates occur poleward of about 30° latitude and of the midlatitude cold desert climates. Such midlatitude steppes are not generally found in the Southern Hemisphere. As with other dry climate regions, rainfall in the steppes is widely variable and undependable, ranging from 20 to 40 cm

43
Q

Effects of climate change

A
  • tropical and subtropical climates to move to higher latitudes
  • El Niño and La Niña move to new regions
    Storm systems are being pushed further into the midlatitudes
  • Jet stream is altering, which brings colder air to lower latitudes and - - warmer air to higher latitudes
  • Migration of animals species
