Cloud Radiative Forcing of the Diurnal Cycle Climate of the Canadian Prairies | Chapter 1 | Emerging Issues in Environment, Geography and Earth Science Vol. 4

 This reasoning uses 40 years of at fixed intervals observations of temperature (T), relative moisture (RH), and opaque cloud cover from 14 atmosphere stations across the Canadian Prairies to resolve the diurnal cycle environment, represented apiece mean T and RH and their diurnal ranges. From April to October, when arriving shortwave radiation dominates over longwave chilling, maximum temperature and the occurring every day ranges of T and RH increase with declining opaque cloud cover, while minimum temperature is nearly independent of cloud. All the while the winter ending, both maximum and minimum temperatures fall accompanying decreasing cloud, as longwave chilling dominates over the net communication by electronic air waves flux, which is shortened by the extreme solar top angle and surface reflection by snow. We pertain the daily mean clouded cloud cover to the longwave and shortwave cloud dragging and the effective cloud albedo, using multiyear calculations of downward communication by electronic air waves and longwave fluxes, and longwave fluxes under clear skies from real weather reanalysis. We provide quadratic fits to calculate effective cloud albedo and net longwave fluxes from clouded cloud cover. During the warm season, the sunshine rise of temperature is related to major computer network radiation, and the darkness fall is related to major computer network longwave cooling. The diurnal range of T, RH, in addition the net radiative fluxes have a almost-linear reliance on the effective cloud albedo. This gives a seasonal mood perspective on the connected land-surface system of T, RH, and cloud cover over the Canadian Grasslands, and the winter transitions in wintry climates.
