As the earth of light has five tokens (the mild zephyr, cooling wind, bright light, quickening fire, and clear water), so has the earth of darkness also five (mist, heat, the sirocco, darkness and vapour).
One of the best indications of actual winter weather, as apart from the arrival of winter by the calendar, is the development of cyclonic disturbances of such strength that the change frcm their warm, sirocco-like southerly inflow hi front of their centre, to the cold wave of their rear produces lion-periodic temperature changes strong enough to overcome the weakened diurnal temperature changes of the cold season, a relation which practically never occurs in summer time.
On the other hand, an ozoneless east wind (sirocco) is occasionally experienced - especially during the second half of May and before the beginning of the rainy season - which has a prejudicial influence on both animal and vegetable life.

The climate, therefore, in parts is exceedingly cold and bleak in winter, and as it is very wind-swept and parched in summer by the terrible qibli or "sirocco" it is much less attractive in appearance than the favoured region on the northern littoral.
Between May and September the sirocco, or hot wind of the desert, sweeps at intervals over the country, impregnating the air with fine sand; but in general, with the exception of the vicinity of the marshes, the climate is healthy.
The chief scourge is the sirocco, which is experienced in its most characteristic form on the north coast, as an oppressive, parching, hot, dry wind, blowing strongly and steadily from the south, the atmosphere remaining through the whole period of its duration leaden-coloured and hazy in consequence of the presence of immense quantities of reddish dust.
On the other hand, the eastern part of this zone is the part of Spain which is liable to be visited from time to time by the scorching leveche, the name given in Spain to the sirocco, as well as by the solano, a moist and less noxious east wind.

Known in Egypt as the khamsin, on the Mediterranean as the sirocco, it is called on the Guinea coast the harmattan.
