There is nowhere quite like Cape Town, The Mother City; it is the perfect blend of grand landscapes and natural wonders, combined with an array of cultures, cuisines and creativity.

The proximity of nature is also a constant source of wonderment here - you can watch zebra and wilderbeasts grazing on the slopes of the world famous Table Mountain from the highway.
Richard C asks: From a previous question about the jet stream I have a problem understanding some key parts of the answer. Why does pressure fall off more slowly in warm air than cold air? And is the fact that this makes higher winds more westerly due to the exaggeration of the effect of the earth's rotation on pressure flow, in which case, can you explain this phenomenon?
It is easy to think of sunburn as something that doesn't really happen in the UK, but it can and it often does.

Simeone Reginald asks: "When I look at forecast maps on westwind.ch that show the height of the 500mb layer and then look at the forecasts of the position of the jet stream, I notice that the jet stream almost always follows the dividing lines between the colder and warmer upper air masses. Does the position of the warm and cold upper air masses determine the route of the jet stream, or does the jet stream determine the position of the cold and warm upper air masses? Which is the chicken and which the egg?"
The measure of how reflective a surface is. Everything from a desert to a forest will have an albedo value, which impacts directly upon the temperature of the air around it.
