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 'Gauss' law seems to imply instantaneous electric field'
Imagine a charged sphere at the origin connected through an open switch to a vertical grounded wire. We wish to find an expression for the horizontal component of the electric field at a distance ##\mathbf{r}## from the sphere as it discharges. By using the Lorenz gauge condition: $$\nabla \cdot \mathbf{A} + \frac{1}{c^2}\frac{\partial \phi}{\partial t}=0\tag{1}$$ we find the following retarded solutions to the Maxwell equations If we assume that...
Hello! Let's say I have a cavity resonant at 10 GHz with a Q factor of 1000. Given the Lorentzian shape of the cavity, I can also drive the cavity at, say 100 MHz. Of course the response will be very very weak, but non-zero given that the Loretzian shape never really reaches zero. I am trying to understand how are the magnetic and electric field distributions of the field at 100 MHz relative to the ones at 10 GHz? In particular, if inside the cavity I have some structure, such as 2 plates...
