* Trade winds: blow from east to west (generally) | |||
* Westerlies: blow from west to east (generally | |||
** these winds defined oceanic travel during the "age of sail" (wind-powered boats) | |||
** they also defined location and direction of European expeditions during the Age of Discovery | |||
*** ex. the Portuguese discovered Brazil because their ships had to sail west, across the Atlantic in order to catch the winds and currents that would then carry their ships south and east to cross the Cape Peninsula and the Cape of Good Hope (southern tip of Africa) | |||
* windward v. leeward | |||
** windward = upwind, or that side facing or nearest to the incoming wind | |||
** leeward = downwind, or that side facing away or furthest from the incoming wind | |||
*** see the Lesser Antilles for the "Leeward" and "Westward" Islands | |||

* waves = oscillations | |||
** waves in water are technically "wind waves" | |||
** water waves are caused by winds | |||
* underwater waves | |||
** ocean floor topography causes underwater waves | |||
** highest underwater waves occur in the Luzon Strait between Taiwan and the Philippines | |||
*** caused by two parallel underwater ridges | |||
*** some underwater waves there can be as high as 1,600 feet | |||
