The intercomparison shows that ERA-Interim exhibits greatest accord with observations in terms of the climatological distribution and seasonality, and all reanalyses exhibit some aspects of the temporal variability and long-term trends as manifest in the observations. Declines in SH prior to 2000 as manifest in the observations appears to have resulted from changes in wind speeds, and the subsequent recovery is attributable to increases in both wind speeds and air-surface temperature gradients. In the climatological mean, SH from observations increases from east to west and exhibits obvious seasonality with highest value in spring and lowest in winter. Spatiotemproal variability in SH over central and eastern TP (CETP) from reanalysis products (i.e., JRA55, ERA-Interim, NCEP1, and NCEP2) and derived using bulk transfer approximations applied to observations is characterized for all seasons during 1980–2015 and is diagnosed in the context of two important drivers of variability: wind speed and land-air temperature difference (Tg-Ta). Sensible capacity is the capacity required to lower the temperature and latent capacity is the capacity to remove the moisture from the air.Surface sensible heat fluxes (SH) over Tibetan Plateau (TP) dictate the seasonal conversion, onset and maintenance of the Asian monsoon. During the cooling cycling, condensation forms within the unit due to the removal of latent heat from the air. It also explains why the terms 'total capacity' (sensible & latent heat) and 'sensible capacity' are used to define a unit's cooling capacity. Heat that causes a change of state with no change in temperature is called latent heat.Īppreciating this difference is fundamental to understanding why refrigerant is used in cooling systems. The heat added to keep the water boiling is latent heat. Latent heat however, does not affect the temperature of a substance - for example, water remains at 100☌ while boiling. The heat that causes these changes is called latent heat. Solids can become liquids (ice to water) and liquids can become gases (water to vapor) but changes such as these require the addition or removal of heat. Heat that causes a change in temperature in an object is called sensible heat.Īll pure substances in nature are able to change their state. Similarly, when heat is removed from an object and its temperature falls, the heat removed is also called sensible heat. The increase in heat is called sensible heat. When an object is heated, its temperature rises as heat is added. Two forms of heat are relevant in air conditioning: ![]()
