On the other side of the mountain. …
Looking at the description of the Chinook winds on the previous thread has given us the perfect example of the differences you can expect when looking at a weather chart.
The town on the left of the mountain is having a wet time of things today. The village on the other side is enjoying a fine day. They are being fed their weather by the same winds.
The same things happen on larger scales. One part of the country is dry and the other is wet. Sometimes it is like that all the year around. Compare British Columbia with Arizona for example.
And sometimes it is planet wide too. Wet weather on the west of Britain seems to go hand in hand with wet weather in parts of Florida. meantime California and central Australia are having a drought.
Then when it stops raining here it starts putting the fires out in California and Australia.
That seems to happen time after time.
I call it the planet's harmonic.
You can watch the wave cross the ocean.
You can watch it cross the continent.
