Can we extrapolate wind speed data to higher altitudes?

Yes, but it may not be valid. The extrapolation will be valid for about 0.1 * PBL Height using the Log-Wind Profile You will need: PBL Height. A second Wind speed (within 0.1*PBL Height) Surface ...

Land's effect on winds and currents?

A few thoughts - assuming like you say that the aqua-planet is the same size as earth, and all else being equal, it's best to consider the two major classes of waves: Nondispersive wind generated ...

When it is said that air moves from warm object to a cold object, how is it possible that air moves from high pressure area to low pressure area?

You are correct that air generally moves along the surface from high pressure towards low pressure (not directly, but deflected due to the coriolis effect). However, this does not imply that it is ...

Land's effect on winds and currents?

They would come to equilibrium, or rather steady state, at which energy input ultimately from the Sun matches energy dissipation by friction. The wind speeds would be somewhat higher because water ...

How to identify low or high pressure area

Because you specifically asked about winds and pressure, there is a fairly applicable rule of thumb. It's called Buys Ballot's Law. Basically, if the wind is to your back (coming behind you), and ...

How long does it take air to circle the world?

It takes about 2 weeks for a mass of air to circle the globe along its latitude from West to east. I used to work for a French climate research lab in the 70s, and was based on Crozet island (South ...

Elevation of Atmosphere differ?

The atmosphere has various layers. Going upwards they are - troposphere, stratosphere, mesosphere, thermosphere, exosphere. (There are "pause" layers between, like tropopause, stratopause etc.) The ...

Intuitive definition of the Monin-Obukhov length?

It is not clear that the Obukhov length has an exact physical interpretation. The length L is certainly a length that dimensional argument shows to follow from the set of basis parameters that Monin ...

What level of heat creates a dust devil?

When a parcel of dry air with a given initial temperature rises, it cools at a specific rate - the dry adiabatic lapse rate. If the surrounding environment cools at a slower rate with height than the ...

Elevation of Atmosphere differ?

The atmosphere, as a whole, is approximately in hydrostatic equilibrium. This means that the gravity of the earth holds the atmosphere to the earth, preventing its escape, though few molecules may ...

How long does it take air to circle the world?

Quick answer is its too vague to give a firm estimate. The geostrophic wind - what the wind would be in theory with no complicating variables, is a function of height, temperature and latitude. There ...

First to Sail the Jet Stream Around the World

It can't be done. That is my guess. I think you would need a pressure suit or cabin. I am a former USAF weather officer with flight experience. I have a Masters Degree in Meteorology and a BS in Space ...
