16.10.3 Uniform-heat-flux pipe For the situation that the pipe is wrapped and furnished with a good heating blanket, we can have an ideal condition called uniform heat flux. In this case, the rate of heat entering the fluid can be expressed as (16.53)Q′=q′A=m′cP(Te−Ti), whe...
The most difficult problem for the satellite-based flux estimation is the retrieval of the air humidity and temperature, qa and Ta, at a level of several meters above the surface. This problem is inherent to all spaceborne passive radiometers, because the measured radiation emanates from relative...
(Fourier’s law) stating that the heat flux (a measure of the quantity of heat) is proportional to the temperature gradient (the difference in temperature between two limiting temperatures). The coefficient of proportionality, called thethermal conductivitycoefficient, is also measured or calculated ...
Under global warming, atmospheric heat transport (AHT) is expected to increase, as warmer air can hold more water vapour enhancing latent heat transport7. Simultaneous OHT changes have an opposing, weakening response, which is not evident from first principles8. When OHU is neglected, OHT and AH...

Total Net Air-Sea Heat FluxThe net heat gain of the ocean is determined by summing the fluxes of shortwave (SR) and longwave radiation (LR) and the turbulent fluxes of sensible (H) and latent heat (LE) at the sea surface. $$NHF = SR + LR + LE + H$$ (20)...
Urban climate, any set of climatic conditions that prevails in a large metropolitan area and that differs from the climate of its rural surroundings. Urban climates are distinguished from those of less built-up areas by differences of air temperature, hu
7. According to the hydrothermal activity models developed in recent years, the rules of the rising height and heat flux of the thermal column were systematically considered. 深海热液活动是当今科学研究的热点,本文基于近年有关热液活动的各种模型,系统分析比较了热液柱的上升高度与热通量等参数变化规律,并...
It was found that, in the case of a typical Scandinavian lake with a size of less than 10 km 2 , the latent heat flux will increase as a function of over-water fetch due to the increase of wind speed and in spite of the increased air humidity. This also has implications on area-...
