South of the Equator there are no tropical storms in these winter months.
The chart shows the mean monthly position of the Intertropical Convergency Zone. The severity of the weather near the Zone depends upon the degree of wind convergence occurring there and varies both in space and time from clear skies, when there is no convergence, to squalls, with heavy rain and thunderstorms, when the convergence is marked.
Only the location and direction of the main ocean currents are indicated. A direct result of this is that, according to whether the wind blows from warmer to colder latitudes, or vice versa, the surface water temperatures will be above, or below, the average for the latitude.
Some idea of the relative warmth or coldness of the currents is given by the extent to which the sea isotherms in the vicinity of the current arrows bend polewards or equatorwards respectively; thus the Benguella Current is obviously cold, the Agulhas Current warm.
In the open ocean, and along leeward shores, sea and air temperatures agree fairly closely within 1 or so ; thus August sea temperature off Scilly is approximately C.
Africa Pilot, Vol. I.
Along windward shores, especially in high latitudes, differences up to 20C. Sometimes the air will be much colder than the sea e.
Sea fog is likely to form wherever warm air passes over cold water; it is most likely to be persistent where the sea isotherms lying athwart the track of a wind blowing from warmer to colder waters are packed closely together.
Areas in which sea fog may be encountered on at least days a month are indicated by a light stipple; days a month areas are shown by a darker stipple.
Ice is about the most variable of all the elements depicted on this chart. The year-to-year fluctuations in the limit of pack-ice or icebergs for that matter are often very considerable. For instance, in some seasons Jan Mayen remains almost completely ice-free; in others it cannot be approached by a ship not specially strengthened, until July.
Icebergs formed by the "calving" of ice from continental ice-caps and valley glaciers are liable to be encountered beyond the pack-ice limits at all seasons of the year, but mostly in early summer. They melt fast once they have drifted into comparatively warm water e.
Over the oceans the only habitually rainy areas are the Doldrums and the storm depression belts of middle and high latitudes. The Trades and N.
Trades, blowing, it will be noticed, off arid lands, are practically rainless. Marine Tracker Tracker Archive.
