How did Köppen define dry climate?
Dry (B) Dry climates are the only category in the Koppen climate classification that isn't entirely based on temperature. They are characterized by having a shortage of water with a low annual mean precipitation rate because water evaporates quickly from its temperatures.

What was Wladimir Köppen's greatest achievement?
His greatest achievement came in 1900, when he introduced his mathematical system of climatic classification. Each of five major climate types was assigned a mathematical value according to temperature and rainfall. Since then, many of the systems introduced by other scholars have been based on Köppen’s work. Wladimir Köppen.
What is a type B climate?
Type B designates climates in which the controlling factor on vegetation is dryness (rather than coldness). Aridity is not a matter of precipitation alone but is defined by the relationship between the precipitation input to the soil in which the plants grow and the evaporative losses.
How high is the elevation of the highland climate?

What is a temperate climate?
Temperate (C) Temperate climate types take the middle road for average temperature. These types of climates are common along the edge of continents. For example, coastal locations have moderate changes in temperature with mild winters and summers. Seasonal changes aren’t as extreme as dry climates.
What is the average temperature of a continent?
Continental climates are usually situated in the interior of continents. They have at least one month with an average temperature below 0°C. Likewise, at least one-month averages above 10 °C.
Koppen Climate Classification System
The Koppen Climate Classification System divides the world into zones based on the distance from the equator in order to describe the long-term weather patterns, or climates. Climates are classified into five main groups, called zones, starting at the equator and working outwards.
Koppen Climate Zones
The Koppen Climate Zones are tropical, dry, temperate, continental, and polar and they correspond to letters A, B, C, D, and E, respectively. Zone A is the closest to the equator and Zone E is the farthest from the equator. Each zone is subdivided further based on temperature and dryness.
Subcategories of Koppen Climate Zones
Each of the five zones, A, B, C, D, and E, are further divided into subcategories to account for variations within each zone. Lowercase letters f, m, s, and w are subcategories describing patterns of rainfall only used for the moist climates: zones A, C, and D. Zone B is divided into S and W and further subdivided by h and k.
Summary
Overview
The Köppen climate classification scheme divides climates into five main climate groups: A (tropical), B (dry), C (temperate), D (continental), and E (polar). The second letter indicates the seasonal precipitation type, while the third letter indicates the level of heat. Summers are defined as the 6-month period that is warmer either from April–September and/or October–March while winter is the 6-month period that is cooler.
Group A: Tropical/megathermal climates
Tropical climates are characterized by constant high temperatures (at sea level and low elevations); all 12 months of the year have average temperatures of 18 °C (64.4 °F) or higher; and generally high annual precipitation. They are subdivided as follows:
All 12 months have an average precipitation of at least 60 mm (2.4 in). These climates usually occur within 10° latitude of the equator. This climate has no natural seasons in terms of thermal …
Group B: Dry (desert and semi-arid) climates
These climates are characterized by the amount of annual precipitation less than a threshold value which approximates the potential evapotranspiration. The threshold value (in millimeters) is calculated as follows:
Multiply the average annual temperature in °C by 20, then add
1. 280 if 70% or more of the total precipitation is in the high-sun half of the yea…
Group C: Temperate/mesothermal climates
In the Köppen climate system, temperate climates are defined as having an average temperature above 0 °C (32 °F) (or −3 °C (26.6 °F), as noted previously) in their coldest month but below 18 °C (64.4 °F). The average temperature of −3 °C (26.6 °F) roughly coincides with the equatorward limit of frozen ground and snowcover lasting for a month or more.
Group D: Continental/microthermal climates
These climates have an average temperature above 10 °C (50 °F) in their warmest months, and a coldest month average below 0 °C (or −3 °C (27 °F), as noted previously). These usually occur in the interiors of continents and on their upper east coasts, normally north of 40°N. In the Southern Hemisphere, group D climates are extremely rare due to the smaller land masses in the middle latitu…
Group E: Polar climates
In the Köppen climate system, polar climates are defined as the warmest temperature of any month is below 10 °C (50 °F). Polar climates are further divided into two types, tundra climates and icecap climates:
Tundra climate (ET): Warmest month has an average temperature between 0 and 10 °C. These climates occur on the northern edges of the North American …
