Subtropical zone

These are the climates that are typically found toward the more equatorial portion of the temperate zone between 23.5° and 35° north or south, and thus are far more influenced by the tropics than any other temperate climate type, usually having warmer temperatures over the year, longer and hot summers and mild, short winters. Freezing precipitation is uncommon in this portion of the temperate zone. In the coolest month, the mean temperature in the subtropical zone is around 8 C (46 F) while in the hottest months mean temperatures are in the 26.5 C (80 F) range.


Humid subtropical (Cfa) and monsoon subtropical (Cwa) climates

Subtropical highland climates (Cfb, Cwb)

Subtropical highland climates are variants of the subtropical climates found in high altitude plateaus or montane systems either in the tropics or subtropics, they have characteristically mild temperatures year-round, featuring the four seasons in the subtropics and no marked seasons in the tropics, the latter usually remaining mild to cool through most of the year.


Middle latitude zone

These climates occur in the middle latitudes, between approximately 35° and 66.5° north and south of the equator. There is an equal climatic influence from both the polar and tropical zones in this climate region. Two types of climates are in this zone, a milder oceanic one and more severe seasonal continental one. Most prototypical temperate climates have a distinct four-season pattern, especially in the continental climate sector.


Oceanic and continental climates

s are created by the on-shore flow from the cool high latitude oceans to their west. This causes the climate to have mild summers and cool (but not cold) winters, and relative humidity and precipitation evenly distributed throughout the year. These climates are frequently cloudy and cool, and winters are milder than those in the continental climate. Regions with oceanic climates include

s in contrast are created by large land masses and seasonal changes in wind direction. This causes continental climates to have severe temperatures for the season, meaning a hot summer and cold winter. Precipitation may be evenly distributed throughout the year, while in some locations there is a summer accent on rainfall. Regions with continental climates include southeastern Canada, the upper portions of the eastern

Subpolar zone

These are temperate climates that compared to the subtropics are on the poleward edge of the temperate zone. Therefore, they still have four marked seasons including a warmer one, but are far more influenced by the polar zones than any other but the very polar climates ( tundra and ice cap climate).


Subpolar oceanic (Cfc, Cwc, Csc)

Areas with subpolar oceanic climates feature an oceanic climate but are usually located closer to polar regions. As a result of their location, these regions tend to be on the cool end of oceanic climates. Snowfall tends to be more common here than in other oceanic climates. Subpolar oceanic climates are less prone to temperature extremes than

Agriculture

Farming is a large-scale practice in the temperate regions (except for boreal/subarctic regions) due to the plentiful rainfall and warm summers, because most agricultural activity occurs in the spring and summer, cold winters have a small effect on agricultural production. Extreme winters or summers have a huge impact on the productivity of agriculture which is less common.

Temperate regions have the majority of the world's population, which leads to large cities. There are a couple of factors why the climate of large city landscapes differs from the climate of rural areas. One factor is the strength of the absorption rate of buildings and asphalt, which is higher than that of natural land. The other large factor is the burning of fossil fuels from buildings and vehicles. These factors have led to the average climate of cities to be warmer than surrounding areas.
