Due to differential heating, it was argued, a tidally locked planet would experience fierce winds with permanent torrential rain at the point directly facing the local star, the subsolar point.

The reverse occurs on the winter solstice in the Northern Hemisphere when the subsolar point will be on the Tropic of Capricorn 23.44�S and a vertical stick will cast no shadow along that point.

Within the tropics, the sun appears directly overhead ( called the subsolar point ) from days to months before the solstice and again after the solstice, which means the subsolar point occurs twice each year.

The "'Tropic of Capricorn "'( or the "'Southern Tropic "') is the circle of latitude that contains the subsolar point on the December ( or southern ) solstice.

One of these subsolar points is Caloris Planitia ( " hot basin " ), appropriately named because an observer near its centre would see the Sun loop around the zenith once per Mercurian day, and hence experience a very hot day indeed.

This ratio would be 1 for the subsolar point, the point on the planet directly below the sun and gives the maximum temperature of the planet-- a factor of 1.414 greater than the effective temperature of a rapidly rotating planet.
19.
The solar noon shadows of objects on points beyond and below subsolar points will point towards true north and true south respectively only when the solar declination has its maximum positive ( ? & = + 23.44?) or maximum negative ( ? & = " 23.44?) value.
20.
On the vernal equinox, north of the subsolar point ( on the equator ) the vertical stick's shadow will point a little westwards of true north ( NNW ) reading 336.5?from true north and little eastwards of true south ( SSE ) reading 156.5?from true north.
