为什么赤道附近表层海水会自东向西流，而深层却反过来？
Why does surface water near the equator flow west but the deep layer flow reverses?
信风把赤道表层水向西推，西边海水堆积下沉后，在温跃层下方又向东回流，形成赤道潜流（如克伦威尔流），表层与深层方向相反。
Trade winds push surface water westward; where it piles up and sinks in the west, it returns eastward below the thermocline as an equatorial undercurrent, so surface and deep flows oppose.

海面上的洋流主要是被什么推着走的？
What mainly pushes surface ocean currents along?
主要是风。信风和西风在海面摩擦，把上层海水吹动，再加上地球自转的科里奥利力让水流偏转，于是形成巨大的环流圈（洋流环）。
Mainly wind. Trade winds and westerlies drag the surface water via friction, and Earth's rotation (Coriolis force) deflects the flow, creating huge gyres.

墨西哥湾流为什么让欧洲冬天比同纬度的加拿大暖和？
Why does the Gulf Stream make Europe milder than Canada at the same latitude?
湾流把墨西哥湾的温暖海水一路送到北大西洋，把热量从低纬带给欧洲沿岸，所以西欧冬天比同纬度的加拿大东岸温暖得多。
The Gulf Stream carries warm water from the Gulf of Mexico across the North Atlantic, delivering heat to Europe's coast, so western Europe is far milder than Canada's east coast at the same latitude.

为什么北半球的洋流会向右拐弯？
Why do ocean currents in the Northern Hemisphere curve to the right?
因为地球在自转，会让运动的物体发生偏转，北半球的偏转方向是向右，所以洋流和风都向右拐。
Because Earth rotates, which deflects moving things to the right in the Northern Hemisphere, so both winds and currents bend rightward.
