At the top of the earth's atmosphere during the early summer (Northern Hemisphere), above what latitude would you expect to receive the most solar radiation in one day? During the same time of year, where would you expect to receive the most solar radiation at the surface?

Therefore, for temperate areas in the northern hemisphere, spring begins on 1 March, summer on 1 June, autumn on 1 September, and winter on 1 December. For the southern hemisphere temperate zone, spring begins on 1 September, summer on 1 December, autumn on 1 March, and winter on 1 June.

During the equinoxes every location on our Earth (except the extreme poles) experiences 12 hours of daylight and 12 hours of darkness. The vernal or spring equinox occurs in the northern hemisphere on March 21 or 22 (the fall equinox of the southern hemisphere).

June 21 is called the summer solstice in the Northern Hemisphere and simultaneously the winter solstice in the Southern Hemisphere. Around December 21 the solstices are reversed and winter begins in the northern hemisphere.

Have you ever wondered why the earth experiences Fall, Winter, Spring, and Summer? Generally, the Northern Hemisphere will experience different climate conditions than the Southern Hemisphere. For instance, one hemisphere will experience the cold conditions of winter while the other hemisphere experiences the warmer conditions of summer.

Regardless of the time of year, the northern and southern hemispheres always experience opposite seasons. This is because during summer or winter, one part of the planet is more directly exposed to the rays of the Sun (see Fig. 1) than the other, and this exposure alternates as the Earth revolves in its orbit.

June 20-21 is one of two solstices, days when the rays of the sun directly strike one of the two tropical latitude lines. June 21 marks the beginning of summer in the northern hemisphere and simultaneously heralds the beginning of winter in the southern hemisphere. In 2014, the summer solstice occurs and summer begins in the Northern Hemisphere on Friday, June 21 at 6:51 a.m. EDT, which is 10:51 UTC.

Confidence votes 54. As everyone knows the Earth tilts on it's axis at the angle of 66 and half degrees. On 21st December the Earth tilts on it's axis so that the sun would hit the southern hemisphere and then the southern hemisphere would have winter while the northern hemisphere would have winter. So when the sun's rays hit the northern hemisphere then the northern hemisphere would have summer while the southern hemisphere would have winter.
http://www.answers.com/Q/Why_does_the_southern_hemisphere_experience_winter_and_summer_solstice_in_different_times_than_of_the_northern_hemisphere
It is the tilt of the Earth that causes the Sun to be higher in the sky during the summer months which increases the solar flux. However, due to seasonal lag, June, July, and August are the hottest months in the northern hemisphere and December, January, and February are the hottest months in the southern hemisphere.
https://en.wikipedia.org/wiki/Season
When the northern half of Earth is tilted toward the Sun, the southern hemisphere is tilted away. People in the southern hemisphere experience the shorter day lengths and colder temperatures of winter. During winter in the northern hemisphere, our northern axis continues to point to the North Star, but, because we have moved in our orbit around the Sun, our northern hemisphere now points away from our Sun.

when the northern hemisphere experiences summer, the southern hemisphere experiences
The southern hemisphere experiences winter when the northern hemisphere experiences summer. When the northern hemisphere experiences summer, the southern hemisphere experiences winter.
