Taking Notes On Wind

Berkeley, Wednesday, October 29, 2025 0:41 AM

Small distraction on downloading an app related to prior post.

Ok. About this. I also would like to go to bed soon. There is heavy machinery in front of my place, who will start working at 8 am.

Query: wind and atmospheric pressure

The goal is to get to point to explain wind simply.

Air pressure means that near the ocean or at sea level air pressure is higher. Air pressure decreases with elevation.

Warm air moves from high pressure to low pressure. But that also opens the space to new dense a cooler air (probably this concept) to fill that gap.

As air moves from warmer temperatures to cooler temperatures it gets deflected.

This is because the earth moves west to east, at a speed of 1,600 kilometers per hour at the equator.

Earth rotation speed decreases as distance increases from the equator.

Does air also get deflected by topography? Probably yes. And that is why there a gust winds as well?

The effect of that the eath changes its horizontal speed, which makes sense, rotate a chord and messure its speed near your hand, axis, and at the most outer end of the chord. This effect makes those wind currents or being deflected on a north east direction in the northen hemisphere and on a south east direction in the southern hemisphere.

That also explain why a cyclone, which in the flow of this explanation makes more sense, although I need to see the etymology of hurricane. Anyways, this deflection explains why the eye or the wall of a cycle or hurricane rotates counter clockwise in the Northern Hemisphere and clockwise in the southern hemisphere.

Although, I believe I understood a few things. Still, I need to understand better the atmosphere, its pressure gradients, temperature, and wind. I might need to understand that phenomenon without earth rotation first. I think the impact of earth rotation or Coriolis effect on wind direction that part is fully clear.

So, many more things to learn. While I cook, I might hear a lectures on this topic in Kanopy. Query, I believe is above.

Further questions I have earth surface rotation speed, and atmospheric speed.

Probably see course, for now:
