How does wind change horizontally and vertically across hundreds of meters?
I'm running experiments in an open field where I'm shooting objects to ranges of up to 300 m, 120 m high. I need to hit a target precisely as possible, so I want to model the wind profile across the ...

Harvesting hurricane energy?
I have seen Can wind turbines stabilize droughts? and it started me thinking. Obviously, the energy involved in a hurricane is much too big to be even scratched by wind turbines, and the tall, ...

Can wind turbines stabilize droughts?
A long good weather period is often combined with little wind. It seems that it needs some wind to end it. Thunderstorms have self-reinforcing dynamics. May droughts be ended by self-reinforcing ...

Can there be wind and/or liquid currents driven by a planet's rotation?
Can the rotation of a planet alone provoke any kind of wind or liquid current? Can the atmosphere, at least in some cases, have wind currents driven by the planet's rotation? And can liquids also move ...

How to compare the ERA5 hourly wind speed wind observed values?
I aim to compare ERA5's hourly wind speed data at a height of 10 meters with observational data. However, the observed wind speed represents a 10-minute average value. My question is: can these two ...

definition of cycles and variabilities used in climate studies, meteorology and oceanography
The definitions of annual cycle, semi-annual cycles etc.. and variabilities such as annual, inter-annual, intra-annual are so fluid and confusing. Let me explain. Annual cycle is defined as any ...

How to calculate horizontal wind shear (esp. via Python)?
I would like to ask about horizontal wind shear. In most cases, we frequently talk about vertical wind shear (VWS), which is the change in wind speed and direction with height or within a given layer/...

For glacier winds to exist, are circulation cells needed?
When air close to a glacier surface gets cooled, it becomes heavier and flows down the glacier slope as glacier winds. I am a glaciologist trying to study and model glacier winds. I am confused about ...

Where can I find high resolution sea surface wind data?
I have been looking for high temporal and spatial resolution surface wind data. I want to use it for competitive sailing simulation, so the temporal resolution should be less than 10 s, the special ...

What can be determined about wind conditions by examining ripples on a body of water?
I am interested in the fractal patterns of ripples and waves, especially on relatively calm bodies of water. Are there empirical or theoretical descriptions of wave speed based on frequency ...

How do lee waves form?
I know that they are caused (usually) by winds flowing up an orographic lift, but why does the up-and-down motion continue after surpassing the mountain?

Oxygen concentrations in the air and absorption rates at sea, even under windy conditions
If I measure the amount of oxygen in the air at sea, is it the same as if I measure it on land? What if there is wind? Does oxygen concentration, change, in the middle of wind? What about the ability ...

Providing wind direction with wrf-python package
I understand that wrf.getvar will give both the speed (dim 0) and the direction (dim 1) V1 = wrf.getvar(ncdin, "uvmet10_wspd_wdir", units="m s-1",timeidx=wrf.ALL_TIMES,meta=False)[...

Wind direction statistics
I evaluate the performance of the model through the computation of statistical parameter such as bias, R, IOA and other. (i compare it with in situ measurements) However, wind direction (range 0 to ...
