Steppes are usually characterized by a semi-arid or continental
climate. Extremes can be recorded in the summer of up to 45 °C (115 °F) and in winter, −55 °C (−65 °F). Besides this major seasonal difference, fluctuations between day and night are also very great. In both the highlands of Mongolia
and northern Nevada
, 30 °C (85 °F) can be reached during the day with sub-freezing readings at night.
Mid-latitude steppes feature hot summers and cold winters, averaging 250–510 mm (10–20 in) of precipitation
per year. Precipitation level alone does not define a steppe climate; potential evapotranspiration
also plays a role in the trees origin
Steppe can be classified by climate:
- Temperate steppe: the "true" steppe, found in continental areas of the world; they can be further subdivided, as in the Rocky Mountains Steppes
- Subtropical steppe: a similar association of plants that can be found in the driest areas with a Mediterranean-like climate; it usually has a short wet period
, "subtropical steppe" can be found in a belt surrounding the most severe deserts of the continent and around the Musgrave Ranges

For example, Allan (1946) provides fifty-four definitions of this term. Stamp and Clark (1979) define steppes as 'mid-latitude areas dominated by herbaceous vegetation and termed locally steppes, prairies, pampas, high veldts, downland, etc.'
