The direction of the mean annual isobars shows that the normal wind in all parts of England and Wales must be from the south-west on the west coast, curving gradually until in the centre of the country, and on the east coast it is westerly, without a southerly component.
Long, and shelters the anchorage from southerly storms. A mole extending from the N.E.
South of Sarakhs, and the most southerly point of the boundary (where it crosses the Kushk) is about 60 m.
Above Inveraray, to the mouth on the Sound of Bute, it has a south-westerly and then southerly trend and is 44 m.
After traversing North Italy, in a direction first southerly and then easterly, it falls into the Adriatic at Porto Fossone, a few miles north of the mouth of the Po.
Lat., thence in an irregular southerly direction across the Cordillera de Merida to the source of the Sarare, whence it runs eastward along that river, the Arauca, and the Meta to the Orinoco.
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.
But what properly forms the western bit of the Alps runs, from near Turin to the Col de Tenda, in a southerly direction, then bending eastwards to the Col d'Altare that divides it from the Apennines.
The rains, however, are prolonged some three or four weeks later than in tracts to the north of the Satpuras, since they are also brought by the easterly winds which blow from the Bay of Bengal in October and the early part of November, when the recurved southerly wind ceases to blow up the Gangetic valley, and sets towards the south-east coast.
The equable temperature is largely the effect of the network of bays, bayous and lakes, and throughout the state the climate is materially influenced by the prevailing southerly winds from the Gulf of Mexico.
