Google - what is wind depression?

When a body of air ascends, the rotation of the earth makes it revolve like an upside-down whirlpool. Then all along this region, bodies of air are being established, in some cases thousands of kilometers across, which are circulating upward, causing low pressure at sea level, clouds and sometimes strong winds. They are called cyclones, and play an important part in moving rain-bearing clouds over the land. That is why,even if the old-time sailors would complain, we can be grateful for this weather system. Similar low-pressure areas are formed where the polar easterlies meet with the prevailing westerlies, where two bodies of air of different temperatures react, or even over locally heated areas. Mark 6:45-51 tells us who have power over the wind. There will come a time in the future the winds will be under his control and will not cause the damage we see today.
