South Africa is a sunny country, averaging 8–10 daily sunshine hours in most regions. [2] The average annual rainfall for South Africa is about 464 mm (compared to a global average of 950 mm [3]) but large and unpredictable variations are common. Overall, rainfall is greatest in the east and gradually decreases westward, with some semi-desert ...
In meteorology, the synoptic scale (also called the large scale or cyclonic scale) is a horizontal length scale of the order of 1,000 km (620 mi) or more. [1] This corresponds to a horizontal scale typical of mid-latitude depressions (e.g. extratropical cyclones ).
The Todd Weather Folios are a collection of continental Australian synoptic charts that were published from 1879 to 1909. The charts were created by Sir Charles Todd's office at the Adelaide Observatory. In addition to the charts, the folios include clippings of newspaper articles and telegraphic and handwritten information about the weather.
Sirocco (/ s ɪ ˈ r ɒ k oʊ / sih-RO-koh) or scirocco is a Mediterranean wind that comes from the Sahara and can reach hurricane speeds in North Africa and Southern Europe, especially during the summer season.
In a barometric col, the winds are relatively calm and varying in direction. The weather is also unsettled and favourable for winter fog or summer storms due to the accumulation of moisture in the air mass due to lack of ventilation. It is thus often the position of a stationary or quasi-stationary front.
Tiffendell Resort, in the Drakensberg, is the only commercial ski resort in South Africa, and has "advanced snow-making capability" allowing skiing for three months of the year. [32] The Mountain Club of South Africa (MCSA) and the Mountain and Ski Club (MSC) [33] of the University of Cape Town both have equipped ski huts in the Hex River ...
A humid subtropical climate is a subtropical-temperate climate type, characterized by long and hot summers, and cool to mild winters. These climates normally lie on the southeast side of all continents (except Antarctica), generally between latitudes 25° and 40° and are located poleward from adjacent tropical climates, and equatorward from either humid continental (in North America and Asia ...
Currently the peak in solar radiation occurs on June 21, but the peak of the summer monsoon in North Africa occurs a month later in July. A one-month lag such as this should be represented by roughly a 1500 to 2000 year lag in the monsoonal circulation maximum, because a July insolation maximum in a 19,000 to 23,000-year precession cycle occurs ...
