When the Sun is directly overhead (at zenith) the point below it is called nadir.

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.
Averaged through the year, Polar Climates receive the least insolation at the surface. Because these latitudes are tilted further from the sun, solar radiation must pass through more of the atmosphere, and is therefore attenuated.
When sun is overhead its 90 degree. But equatorial region on earth gets more effect.
what location on earth receives roughly the same amount of solar radiation year round
Tropical Climate because it receives a lot of the intense solar energy and it is also most likely to be found near the equator where the sun is directly giving solar energy.
The tropical climate zone receives the highest insulation.
Because the sunlight it receives is almost directly overhead all year round. the Equator receives the most solar energy.
the area of direct insolation
This region receives the most nearly perpendicular insolation.
The period of time that a surface receives solar energy. The number of daylight hours.

There is no 'why' because that statement is false. The equator is right in the CENTER of the tropics. As the sun wiggles back and forth between the edges of the tropics each year, the equator is the place that receives the MOST average insolation.
How long it is daylight. In the summer, it's longer than in the winter.The period of time that a surface receives solar energy. The number of daylight hours.
What provider receives reimbursement for Medicare directly from the fiscal intermediary? QIO - Quality Improvement Organization
it stays fairly constatnt throughout the year because it receives the same amount of direct light all year round (the light hits it almost directly overhead) but it can plummet significantly during rainstroms
