Climographs

A climograph combines a line graph of mean monthly temperature with a bar graph of total monthly precipitation. These graphs are useful in analyzing climate statistics to determine the climate classification.

A Climates
tropical wet

Description: tropical wet (Af) [tropical rainforest]--hot humid wet all year-- > 2.4" (6 cm) per month; MONOTONOUS
Note: The high temperature with little variation and notable precipitation every month.
tropical monsoonal

Description: tropical monsoonal (Am)--short dry season, very wet rainy season with high concentration in a few months--at least one month under 2.4" (6 cm)
Note: The high temperature with little to small amounts of variation and a short time with low precipitation but excessively heavy precipitation for part of the year that compensates for the short drought period.
tropical savanna

Description: tropical savannah (Aw)--hot, humid but dry season in winter and longer;--at least one month under 2.4" (6 cm)--most extensive A climate
Note: The high temperatures with a small variation and a dry season without a very heavy period compensating for the dry season.

B Climates
low latitude desert

Description: low latitude desert (BWh) [subtropical]--between 0 and 15" precipitation average annual temperature is over 64.4F (18C)--SCARCE; UNRELIABLE; INTENSE PRECIPITATION
Note: The very low amounts of precipitation and the high temperatures.
midlatitude desert
Description: midlatitude desert (BWk) [high latitude]--between 0 and 10" precipitation and average temperature under 64.4F
Note: The low amount of precipitation and the middle ranging temperatures.
low latitude steppe
Description: low latitude steppe (BSh) [subtropical]--between 15 and 30" precipitation and average annual temperature over 64.4F (18C)
Note: The lack of precipitation and the high temperatures.
midlatitude steppe
Description: midlatitude steppe (BSk) [middle latitude]--between 10 and 20" precipitation and average annual temperature under 64.4F (18C)
Note: The lack of precipitation and the middle ranging temperatures.

C Climates
humid subtropical

Description: humid subtropical (Cfa, Cwa)--hot summer, mild winter; may be dry winter; warmest month averages above 71.6F (22C) and coldest month averages less than 64.4F (18C) but greater than 32F (0C)
Note: The middle temperature range with no month below freezing and notable precipitation every month.
marine west coast

Description: marine west coast (Cfb, Cfc)-ocean current moderates, mild summer and winter; warmest month averages below 71.6F (22C) and coldest month averages less than 64.4F (18C) but greater than 32F (0C) Note: The middle temperatures with a limited amount of variation and the wet conditions.
mediterranean

Description: mediterranean (Csa, Csb)--warm, dry summer, mild, moist winter or hot summer has drought, winter precipitation but not freezing; sometimes known as dry (summer) subtropical; coldest month averages less than 64.4F (18C) but greater than 32F (0C) difference is the summer drought
Note: The middle temperatures with a DROUGHT during the high sun season (summer)

D Climates

humid continental
Description: humid continental (Dfa, Dfb, Dwa, Dwb)--cold winter, warm summer, precipitation all year; at least four months average over 50F (10C) and coldest month averages below 32F (0C)
Note: The lower temperatures with temperatures below freezing and notable precipitation all months.

subarctic
Description: subarctic (Dfc, Dfd, Dwc, Dwd)--cold and snow, three or less months average over 50F (10C)--WINTER--taiga, boreal; GREATEST RANGE
Note: The large range of temperature with temperatures below freezing some months and notable precipitation all months.

E Climates
tundra
Description: tundra (ET)--cold, low-growing shrubs and herbs; one month averages above 32F (0C) but less than 50F (10C); but all average below 50F--TREE LINE; permafrost
Note: The cold temperatures with temperatures only reaching above freezing and not to 50° and the lack of precipitation because of these cold temperatures.

ice cap
Description: ice cap (EF)--all months average below 32F (0C); ice and snow covered--(Greenland, Antarctica); LOWEST TEMPERATURE
Note: The very cold temperatures and the lack of precipitation because of these cold temperatures.


F or H Climate

highland
Description: highland (H or F)--altitude, exposure (sun and wind), CHANGABILITY
Note: Highland climates are noted for an anomaly in the appearance of the climograph. Because higher elevations have a lower average temperature and a greater range in temperatures as well as experiencing the orographic effects of precipitation, the typical patterns appear disrupted. In this example, the temperatures are fairly uniform but at a cooler temperature than the typical uniform equatorial hot temperatures.
