Wind

Did you ever wonder where the wind comes from? Sometimes it gently caresses your face and at times it blows so hard against us it makes us move. I have often felt wind on my face and wondered where did it come from.Cool wind can be a friend on a hot summer day, but what ever it does have its purpose here on earth. Those friendly winds can be disastrous in storms, such as tornadoes and hurricanes.

What causes the air to move? It's the uneven heating of the earth' atmosphere. Different levels of heat on the surface of earth is the main cause of wind. The energy in wind comes from the sun. When the sun shines some of its light reaches the earth's surface. Warm air, which weighs less than cool air, rises. So then the cold air moves in and takes over the warm rising air. That movement of air is what causes wind to blow. All different winds are caused by different air pressure. Different levels of heat on the surface of earth is the main cause of wind, also the spin of the earth adds a small amount of winds, orbiting pull of the moon causes some wind (even more the tides).

I was surprised to find the source of the wind was the sun. But might of known that the sun it has a tremendous effect here on earth. It was interesting to find this out, because I have always wondered what suddenly caused that light brush of wind on my face, was it some mystical creature playing a joke by blowing in my face.

Thanks for the visit to Lincoln Doodles. I didn't expect anybody to find it so soon.

I have read a lot about the earth and saw even more on television now that we have cable and get better stations. I like the history, learning, discovery and science channels.

Hi Margaret, I had missed you and wondered? I am so sorry your husband has been having troubles. People don't realize how your mate's illness can be so taxing on us. The worry gets us down. I know because Bobby G. has medical issues and I worry to no end. So I am happy things are getting better and you can get back to blogging. Love your wind post. Today we had the perfect light breeze, moderate temps and warm sunshine. Much love, Lynn

Hmmm.... interesting! But I still hate wind. Always have. I'd take a completely still, calm day any day over a windy one, even in the summer. We just have far too much wind here in central Illinois - it's windy at least 6 days out of 7 each week. Yuck. But I'll try to remember, the sun is the cause. :o)

Glad to see you back posting.

Hi again Margaret, so glad you stopped by for a visit today. Yes, everything is still topsy turvy and will be probably for another couple of months. It's so slow going on repairing all the walls. Seems like they got very little done today even though they were here at 8 am and still working but I guess that's the nature of the work. I am trying to be patient. :) How is your husband? Doing well I hope. xo
