<P>The term <I>trade winds</I> originally derives from the early fourteenth century late <A href="/wiki/Middle_English" title="Middle English">Middle English</A> word 'trade,' meaning "path" or "track."<SUP id="cite_ref-1" class="reference"><A href="#cite_note-1">[1]</A></SUP> The Portuguese recognized the importance of the trade winds (then the <I><A href="/wiki/Volta_do_mar" title="Volta do mar">Volta do mar</A></I>, meaning in Portuguese "turn of the sea" but also "return from the sea") in navigation in both the north and south Atlantic ocean as early as the 15th century.<SUP id="cite_ref-2" class="reference"><A href="#cite_note-2">[2]</A></SUP> From West Africa, the Portuguese had to sail away from continental Portugal, that is, to west and northwest. They could then turn northeast, to the area around the <A href="/wiki/Azores" title="Azores">Azores</A> islands, and finally east to mainland Europe. They also learned that to reach South Africa, they needed to go far out in the ocean, head for Brazil, and around 30°S go east again. Following the African coast southbound means upwind in the Southern hemisphere. In the Pacific ocean, the full wind circulation, which included both the trade wind easterlies and higher-latitude <A href="/wiki/Westerlies" title="Westerlies">Westerlies</A>, was unknown to Europeans until <A href="/wiki/Andres_de_Urdaneta" class="mw-redirect" title="Andres de Urdaneta">Andres de Urdaneta</A>'s voyage in 1565.<SUP id="cite_ref-pg18_3-0" class="reference"><A href="#cite_note-pg18-3">[3]</A></SUP></P>
<P>The captain of a sailing ship seeks a course along which the winds can be expected to blow in the direction of travel.<SUP id="cite_ref-4" class="reference"><A href="#cite_note-4">[4]</A></SUP> During the <A href="/wiki/Age_of_Sail" title="Age of Sail">Age of Sail</A>, the pattern of <A href="/wiki/Prevailing_winds" title="Prevailing winds">prevailing winds</A> made various points of the globe easy or difficult to access, and therefore had a direct effect on European empire-building and thus on modern political geography. For example, <A href="/wiki/Manila_galleon" title="Manila galleon">Manila galleons</A> could not sail into the wind at all.<SUP id="cite_ref-pg18_3-1" class="reference"><A href="#cite_note-pg18-3">[3]</A></SUP></P>
<P>By the 18th century the importance of the trade winds to England's merchant fleet for crossing the Atlantic Ocean had led both the general public and etymologists to identify the name with a later meaning of 'trade', "(foreign) commerce".<SUP id="cite_ref-5" class="reference"><A href="#cite_note-5">[5]</A></SUP> Between 1847 and 1849, <A href="/wiki/Matthew_Fontaine_Maury" title="Matthew Fontaine Maury">Matthew Fontaine Maury</A> collected enough information to create wind and current charts for the world's oceans.<SUP id="cite_ref-6" class="reference"><A href="#cite_note-6">[6]</A></SUP></P>

The subsident (sinking) air is relatively dry because as it descends, the temperature increases, but the absolute humidity remains constant, which lowers the relative humidity of the air mass. This warm, dry air is known as a superior air mass and normally resides above a maritime tropical (warm and moist) air mass. An increase of temperature with height is known as a temperature inversion. When it occurs within a trade wind regime, it is known as a trade wind inversion.<SUP id="cite_ref-11" class="reference"><A href="#cite_note-11">[11]</A></SUP></P>
