Macroclimate

 

the climate of large geographic areas such as geographic zones, continents and oceans or large parts thereof, or even the entire earth; macroclimate deals with the main climatic features of these areas. If such a part of the earth’s surface is sufficiently uniform in its geographic factors and conditions of general atmospheric circulation it will have a certain macroclimate. For example, it is possible to speak of the macro-climate of the tradewinds zone, of Eastern Siberia, of the Mediterranean Basin, and the Antarctic Plateau. Macroclimates are characterized by quantitative indexes that refer to the entire area being considered (that is, intervals within which particular climatic characteristics change throughout the area or their average values for the entire area). The macroclimate is contrasted with the local climate and microclimate.

Macroclimatic conditions lend themselves particularly to subdividing the biosphere into large units as the climate is the primary factor which influences all others, both edaphic and biotic.

Most investigators considered broad-scale climate only indirectly, by studying vegetation change along complex-gradients of elevation or latitude, and none explicitly examined relative contributions of regional (macroclimatic) and local (microclimatic) measures of temperature and moisture.
Regardless, the macroclimatic regime has certainly undergone substantial change since the human occupancy of these sites (Svoboda, 1982).
The soils (their species/varieties) determine not only (1) the floral and faunal composition and diversity, (2) the productivity level and related influx of fresh organic matter into the soil, (3) the SOM decomposition intensity and (4) the biological turnover of chemical elements, but also the transforming of areal macroclimatic conditions into the soil (micro)climate, on which an inducing/stagnating intensity of inputted SOM decomposition and transformation depends (Astover et al.

Thus, dry meadows and wet meadows differ primarily in rates of soil resource availability, rather than in macroclimatic conditions, affording an opportunity to directly compare their community composition and diversity responses to fertilization.
