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 southern hemisphere would be 66.5 deg S (Antarctic Circle)
When the northern hemisphere is in winter, the southern hemisphere is in summer.
The hemisphere where it is summer. Northern in July, Southern in Dec.
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.
The earth is closer to the Sun in the southern hemisphere when it is summer, but during summer in the northern hemisphere the earth is farther away by many millions of kilometres . Although this will change gradually and in 13,000 years the opposite will be true .

Tangent rays are the migratory sun rays that skim over the earth's surface at high latitude locations (Polar Regions). These rays also occur during dusk and dawn at any latitude.
Any latitude has tangent solar rays, at local sunrise and sunset. At the appropriate time of year, latitudes greater than 66.5° north or south can experience tangent solar rays at any point in a 24-hour day.
When the northern hemisphere is in winter, the southern hemisphere is in summer.
The hemisphere where it is summer. Northern in July, Southern in Dec.
At the time of the equinoxes, the sun's rays would be nominally tangent to the Earth at the north and south poles. Those are 90 degrees north and south of the equator respectively. Also I think at either 23.5 degrees north or 23.5 degrees south at sunrise and sunset.
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.
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.
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

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.
