how is relative humidity related to geopotential height?

Question

Why would it make sense to group these variables together?

Answer 1

Ok - let me give this one a shot. The geopotential height H is related to the virtual temperature T* of the layer through which H is measured. T* in turn is related to the mixing ratio, w, of the air i.e. the ratio of the mass of water vapor in a given volume of air to the mass of dry air in the volume. Now w is close to but NOT the same as relative humidity, RH, for RH is equal to w/w(s) where w(s) is the saturation mixing ratio of the air at that temperature and pressure. Sorry, but I couldn't answer without this level of difficulty.

Answer 2

that is an exceedingly solid question. dissimilar people get puzzled with appreciate to relative humidity. Relative humidity is a function of ambient temperature (T) and dew aspect temperature (Td). at the same time as both are the similar the RH is 100%. at the same time as both are fairly diverse, the RH is low. So RH oftentimes is at a optimal at evening and early morning and at a minimum on the time of the optimal temperature. Td many situations does no longer form lots throughout the day (there are exceptions). as an get mutually, If T=Td= 10C (50F) then the RH is 100%. this may precise be a project the position that is fairly cool and also you'll be in a position to precise be experiencing fog or dew. I doubt that you will be able to probably adventure sweaty and uncomfortable lower than those circumstances. Conversely, in the tropics if T=35C (95F) and Td=25C (77F) then the RH will be 56%. lower than those circumstances, i'm particular that you will be feeling fairly sweaty and uncomfortable. Tropical elements many situations have higher Dew aspect temperatures, to boot the glaring undeniable reality that Relative Humidity's are harder to generalize. So the more beneficial advantageous the dew aspect temperature, the more beneficial sweaty and uncomfortable you're possibly to be. at the same time as people say "it feels humid in the well-known", it continually ability that the dew aspect temperature is larger than what it many situations is. The link lower than has a relative humidity calculator to boot as some respected definitions of the sorts of humidity.
