The tangent ray refers to either the northernmost or southernmost hemisphere where the vertical rays refers to direct sun. During the June 21 solstice, the latitude rays in the northern hemisphere would be 66.5 degrees N (Arctic Circle)
The northern hemisphere is exposed to vertical rays of the sun during the summer solstice, which occurs around June 21 each year. On this day, the sun is directly overhead at the Tropic of Cancer (23.5° N latitude), resulting in the longest day of the year for the northern hemisphere. After the summer solstice, the sun's rays gradually shift southward, decreasing direct sunlight in the northern hemisphere until the winter solstice in December.
The Northern Hemisphere is tilted toward the sun during summer because of the Earth's axial tilt. This tilt causes the sun's rays to strike the Northern Hemisphere more directly, creating longer days and warmer temperatures. As the Earth orbits the sun, this tilt changes, causing the seasons.
The vertical rays of the sun in the Northern Hemisphere occur at the Tropic of Cancer, which is located at approximately 23.5 degrees North latitude. This is the northernmost point where the sun can be directly overhead at noon, occurring during the summer solstice around June 21.
There is no time between these. On the day before the autumnal equinox, the sun is directly overhead in the northern hemisphere (at a latitude just north of the equator). The following day, it is directly overhead in the southern hemisphere (just south of the equator). The sun goes from being overhead in the northern hemisphere to the southern hemisphere instantaneously, the change happening at the autumnal equinox.
The Earth is close to a sphere so there is but one single point on the sphere that has the Sun directly overhead at any one time. When this point is in the Northern hemisphere (roughly from the 21 of March to the 20 of September) the Southern Hemisphere is less directly hit by the rays of the Sun and experiences somewhat cooler seasons than when the rays of the Sun strike more vertically.

On September 23rd, the sun's rays are directly over the equator, marking the beginning of autumn in the Northern Hemisphere and spring in the Southern Hemisphere. This day is known as the autumnal equinox in the Northern Hemisphere.
If the northern axis or North Pole is tilted directly towards the sun, it is summer in the northern hemisphere and winter in the southern hemisphere. If your talking about the angle of the planet when the Northern Hemisphere is receiving direct rays, its summer. If you are asking what the Northern Hemisphere season it is when planet Earth is closest to the Sun, it's winter.
Whichever hemisphere (the Northern or Southern Hemisphere) is tilted toward the sun receives more direct rays of sunlight (or rays that are closer to perpendicular or a 90° angle). The hemisphere tilted toward the sun also has more hours of daylight than the hemisphere that is tilted away from the sun
Thus, we experience Summer in the northern hemisphere when the Earth is on that part of its orbit where the N. Hemisphere is oriented more toward the Sun and therefore the Sun rises higher in the sky and is above the horizon longer, and the rays of the Sun strike the ground more directly. Likewise, in the N. Hemisphere Winter the hemisphere is oriented away from the Sun, the Sun only rises low in the sky, is above the horizon for a shorter period, and the rays of the Sun strike the ground more obliquely. It is now (fifth May) the season of Spring.
UK is in the northern hemisphere while south Africa is in the southern hemisphere. during december the suns rays fall directly on the southern hemisphere while northern hemisphere gets slant rays hence UK is colder in december than Africa.
The Earths tilt is such that the northern hemisphere is pointing away from the sun more in the winter. The northern hemisphere receives less solar energy as the suns rays hit the earth surface at shallower angles during this time.
The tangent ray refers to either the northernmost or southernmost hemisphere where the vertical rays refers to direct sun. During the June 21 solstice, the latitude rays in the northern hemisphere would be 66.5 degrees N (Arctic Circle)
well if you say it that way, it depend which hemisphere you live in. We live in the northern hemisphere, so the sun rays strike to the southern hemisphere.
The earth rotates on its axis at an angle of about 23.5 degrees. This means that at some times in its orbit one hemisphere is more directly aligned with the sun than the other. Six months later the other hemisphere is more directly aligned.When the hemisphere is more directly aligned, the suns rays are more nearly perpendicular, and so deliver more energy per unit of area, making it warmer. This is the summertime for that hemisphere. It also explains why when it is summer in the northern hemisphere it is winter in the southern hemisphere.
The Northern Hemisphere is tilted toward the sun during summer because of the Earth's axial tilt. This tilt causes the sun's rays to strike the Northern Hemisphere more directly, creating longer days and warmer temperatures. As the Earth orbits the sun, this tilt changes, causing the seasons.
