Point A is not shown, so no answer can be given. Graphics are not allowed on Answer, so in its place, a latitude and longitude, and a description, would help to pin-point, point A.
what is the most convenient reference point for the determination of places in the northern and eastern hemisphere?
equator and also the southern
They point to geosynchronous satellites in orbit above the equator. South for the northern hemisphere and north for the southern.
Well ONE place exists at ONE point on Earth and that ONE point is either in the Southern Hemisphere OR in the Nothern Hemisphere - is is not on BOTH.
The Western Hemisphere, starts in the Greenwich, paralell, and goes past America, any thing that is bellow the equator is south and west from that point.
A compass will point the same whether it is in the northern or southern hemisphere. The needle on a compass is designed to magnetically line up with the earths poles. Therefore the north end of the needle of the compass will point to earths north, and the south end of the compass needle will point towards earths south whether you are in the northern or southern hemisphere.

It is - but the northern hemisphere is also tilted awayfrom the sun at that point, giving us wintertime.

yes it does
northern
At the winter solistice.
None. When spring starts in the northern hemisphere, autumn is starting in the southern hemisphere. There are only ever 2 seasons at any which point in time.
Because of the Magnetic North Pole, a point on the Earth's Northern Hemisphere
At its highest point in the sky, and due South in the Northern Hemisphere.
