semi arid climate graph

Cold semi-arid climates at higher latitudes tend to have dry winters and wetter summers, while cold semi-arid climates at lower latitudes tend to have precipitation patterns more akin to subtropical climates, with dry summers, relatively wet winters, and even wetter springs and autumns. According to Köppen and Geiger, this climate is classified as BSk. In climate classification, three isotherms means that delineate between hot and cold semi-arid climates — the 18 °C average annual temperature or that of the coldest month (0 °C or −3 °C), the warm side of the isotherm of choice defining a BSh climate from the BSk on the cooler side. coldest month averaging below 0 °C (32 °F) and 1–3 months averaging above 10 °C (50 °F). These large diurnal temperature variations are seldom seen in hot semi-arid climates. By Mark New.

Warm Oceanic Climate / Humid Subtropical Climate, Hot Summer Temperatures Greater than or equal to 22 °C. Furthermore, to delineate hot semi-arid climates from cold semi-arid climates, there are three widely used isotherms: either a mean annual temperature of 18 °C (64.4 °F), or a mean temperature of 0 or −3 °C (32.0 or 26.6 °F) in the coldest month, so that a location with a BS type climate with the appropriate temperature above whichever isotherm is being used is classified as hot semi-arid (BSh), and a location with the appropriate temperature below the given isotherm is classified as cold semi-arid (BSk). A more precise definition is given by the Köppen climate classification, which treats steppe climates (BSk and BSh) as intermediates between desert climates (BW) and humid climates in ecological characteristics and agricultural potential. Semi-arid climates tend to support short or scrubby vegetation and are usually dominated by either grasses or shrubs.
