polar easterlies
The wind belts that extend from the poles to 60 degrees latitude in both hemispheres are called the polar easterlies. The polar easterlies are formed as cold, sinking air moves from the poles toward 60 degrees north and south. in the north hemisphere , the polar easterlies can carry cold air which produces snow and freezing. The westerlies can carry moist air over the United States, producing rain and snow .
Air sinks at 30 degrees, then moves south along the surface. At about 60 degrees, air rises and then moves north toward the equator. At 30 degrees, the air sinks again and the cycle starts all over.

You can find the Antarctic Circle at about 66.5628° S. Because the earth wobbles, the circle moves with it.

The Antarctic Circle is a line of latitude -- which moves, according to the Earth's wobble. As of 10 March 2016, it runs 66°33′46.1″ as a line of latitude and crosses all degrees of E and W longitude on Earth.

Many deserts are found in bands along 30 degrees latitude north and 30 degrees latitude south (between the red lines on the map). Some deserts located by mountains and are caused by the "rainshadow" effect. As air moves up over a mountain range, it gets cold and loses the ability to hold moisture -- so it rains or snows. When the air moves down the other side of the mountain, it gets warmer. Warm air can hold lots of moisture, so it doesn't rain as much, and a desert is formed.

The sun's declination migrates manually through 47 degrees latitude. It moves in the middle of the latitudes of Tropic of Cancer and Tropic of Capricorn.
The 30 degree latitude area is at the high pressure region developed by the sinking air from the Hadley Cell created by the low pressure rising air at the equator. Winds move from high to low pressure areas. The doldrums are located at the equator, this is a low pressure area. When the air sinks at the 30 degree latitude air moves away from the 30 toward the equator and 60 degree latitudes. Since air does not move toward the 30, there is no way to bring the maritime air masses to those desert areas.
Assuming the hour hand moves steadily for the entirety of the hour, the angle formed by the hour and minute hand would be 55 degrees.

Hour hand moves 30 degrees, minute hand moves 360 degrees.
Between June 21 and December 21, it moves from 23.5 north to 23.5 south ... 47 degrees of latitude. Then during the other 6 months, it covers the 47 degrees to return back north. But the rate at which it covers this range is not constant. The speed is "sinusoidal" ... slowest at the ends, and fastest in the middle.
