Trade winds the Canary Alisios


The Trade Winds (Vientos Alisios) or Intertropical Winds

The Trade Winds in the Canary Islands – How many times taking a flight and going overseas you may have noticed that the travel times change during one direction rather than in the opposite direction? For example, a Milan-Havana is longer than a Havana-Milan and when we ask the crew we are told that it is due to the trade winds?

It ‘an exemplification of course, but behind there is some truth to this answer, because the shipping lanes (in the case of sailing vessels) or air (in general), differ in one direction rather than another, keep your account the presence of the trade winds and exploit them to optimize travel times and therefore costs.

The trade winds are therefore typically oceanic winds and their role was crucial for example in sailing and for the circumnavigation of the globe.

The trade winds are defined by experts as the winds of the Hadley cell, which is included in a specific band of the tropics, which has in the center of the equator (the intertropical band).

The presence of the trade winds and their way of blowing steadily, means that some regions with an effect of the existence of certain weather situations and therefore falls within the category of trade winds in the so-called synoptic winds.

The directions of trade winds are typically those that go from north-east to south-west in the upper hemisphere (northern hemisphere) or south-east to north-west in the lower one (Southern hemisphere), since the equator is a little from “watershed” in the sense that its component low pressure means that thanks to the rotation of the earth, it generates a force (Coriolis force), which deflects them towards East; winds that converge toward the equator are heated and they rise portion forming masses of moist air and rainy (this is the reason why the equator the climate is unbearable, in addition to the fact hot, moist air is concentrated and rainfall).

Just think what would become of modern civilization without the trade winds and what would be, for example, the great navigators such as Christopher Columbus, if they had known these winds during their explorations …

The trade winds, luck of the Canary Islands

The Anglo-Saxons have them baptized “Trade winds”, which is the trade winds, because thanks to their existence are favored trade between one continent and another, and contrary to the wind Calima (typical Canarian but more often skipping on ‘ Archipelago), represent a treasure in many respects.

In the case of the Canary Islands then, the trade winds (synoptic winds), constant (unlike the monsoon winds, for example, that reverse their direction of travel depending on the season), they ensure great stability control with minimal excursions between seasons and the other, with stable weather conditions and low rainfall that is going to concentrate further south in the direction of the equator …

And ‘This is the phenomenon that constitutes the true good fortune for the entire archipelago, being the origin (and as you will find repeated in various forms in other Articles of the site), the extraordinary climate of the islands and that allows visitors to not suffer ever very hot in summer, nor shivering in the winter, but instead ensure the Canary Islands to enjoy the climate MORE ‘BEAUTIFUL WORLD!
