I Estimating Vertical Wind Speeds: T_a, T_s, & P_a

AI Thread Summary
Estimating vertical wind speeds using data from an automatic weather station, including 2m air temperature, surface temperature, and air pressure, is complex. Key concepts like eddy covariance and the Bowen ratio energy balance are essential, as they relate vertical air movement to evaporation. The hypsometric equation can potentially be used to calculate surface pressure, which may help in relating pressure differences to vertical velocity. A recommended resource for further understanding is the book "Evaporation Into the Atmosphere" by W. Brutseart. Overall, additional variables and a deeper understanding of atmospheric dynamics are necessary for accurate estimations.

TL;DR Summary
Calculate vertical wind speed based upon temperature difference
Hi all,

I have some data from an automatic weather station, with recordings of both 2m air temperature and 2m air pressure and also the surface temperature. Is it possible to estimate vertical wind speeds between the AWS and the surface based upon this data? Imagine T_a = 15 degrees and T_s = 30 degrees and P_a = 670 hPa. If not, which other variables do I need?

Thanks.

It's more complicated than that. I suggest the these search terms to learn more: eddy covariance and Bowen ratio energy balance. These search terms are mostly about evaporation of surface water, and vertical air movement is closely tied to evaporation. A good book on the subject is Evaporation Into the Atmosphere: Theory, History, and Applications, by W. Brutseart (1982). An oldie, but goody, and it's still in print because it is the standard reference in that field: https://www.amazon.com/dp/9027712476/?tag=pfamazon01-20.

Thanks for the answer! I was thinking maybe to calculate the pressure at the surface with the hypsometric equation and then relate the pressure difference to a vertical velocity... is this also possible?
 
Thread 'Question about pressure of a liquid'
I am looking at pressure in liquids and I am testing my idea. The vertical tube is 100m, the contraption is filled with water. The vertical tube is very thin(maybe 1mm^2 cross section). The area of the base is ~100m^2. Will he top half be launched in the air if suddenly it cracked?- assuming its light enough. I want to test my idea that if I had a thin long ruber tube that I lifted up, then the pressure at "red lines" will be high and that the $force = pressure * area$ would be massive...
I feel it should be solvable we just need to find a perfect pattern, and there will be a general pattern since the forces acting are based on a single function, so..... you can't actually say it is unsolvable right? Cause imaging 3 bodies actually existed somwhere in this universe then nature isn't gonna wait till we predict it! And yea I have checked in many places that tiny changes cause large changes so it becomes chaos........ but still I just can't accept that it is impossible to solve...
