Below is a photo I took of my screen whilst watching Windy.com, ome of the best weather apps available. It shows realtime the state of the planets weather.

One of the things that surprises people is that Lows presure zone, you know those areas of the weather that sweep up carrying bad weather into the south West of the British Isles, spins to the left, you casn see this on the wind patterns that surround the lows centre. The high is the calm area that tries to block the path of the Lows progression. Between the two you can see contour lines of presure. The closer together the higher the wind and the location of the low to the high, denotes direction of the wind, its complex, but once you get used to looking at the charts, the more it makes sence.

That is till you look at the Northern Hemisphere where the lows spin to the left, and highs spin to the right. In the Southern Hemisphere to complete opposite occurs, the lows spin to the right, and the Hights spin to the left.

Don’t believe me, take a look at Windy.com and zoom as far out as possible and watch the wind at ground level.

Don’t blame me, its so addictive. Oh is all down to the Coriolis effect, the spin of the earth, the same effect of a child sitting at the centre pole of a spinning top and trying the throw a ball to its friend who is sitting on the edge of the top.

I asked Google Gemini for a simple overview, a 1 paragraph that might help, it came back with this simple view: the full conversation can be seen here: http://bit.ly/48G0zaN

“Think of the Earth as a spinning top: the wide Equator moves much faster (about 1,000 mph) than the narrow Poles just to complete the same daily rotation. When air currents move North or South, they carry that specific momentum with them. In the Northern Hemisphere, air moving toward the poles is ‘faster’ than the ground beneath it, causing it to deflect to the right; this deflection forces air rushing into a Low-pressure center to twist counter-clockwise. In the Southern Hemisphere, the effect is reversed, deflecting air to the left and spinning storms clockwise—exactly like a ball thrown across a spinning merry-go-round appearing to curve because the person catching it has moved.”

It works for me !
