There is an upwelling of nutrient-rich deep ocean water, worldwide changes in climate, and there is also an increase in the plankton and fish population near the coast of Peru to name a few things that happen.
Perth is the most westerly capital city in Australia. Geraldton, a city also on the coast of Western Australia, is slightly further west than Perth.
If you're in an airplane, it's because of prevailing winds.
The Gulf Stream, it being in midlatitude, and westerly winds
If you count the jet stream then the prevailing winds are from West to East making the the West coast the windward side. (This is of course given that the assumption is made over a period of time.) Not taking into account the jet stream, there have been numerious times when the honor has floated between each coast for prevailing winds. So the real question, does it really matter?
The pacific coast from northern California to southern Alaska, which includes British Columbia, has a climate described as marine west coast. This climate is affected by Pacific ocean currents, the coastal mountains, and the prevailing westerlies.
Either the Queen Charlotte Islands, which are off the northern coast of BC, or the Gulf Islands, which are off the southern coast of BC.
From South Africa, travelling westerly along the 30 degrees line of latitude, the nearest continent is the east coast of South America.
The process of longshore drift is waves hit up against the sand and the sand grains are taken by the waves back into the sea and back to shore again, this is called swash ans backwash.
The Westerlies, which are prevailing winds blowing from west to east in the mid-latitudes, can have several effects on mid-latitude coasts. They can cause the upwelling of nutrient-rich water along the coast, leading to increased productivity and a diverse marine ecosystem. The Westerlies can also drive wave action and create strong currents, affecting sediment transport and erosion along the coastline. Additionally, these winds can influence weather patterns and storms, leading to changes in coastal climate and precipitation patterns.
The prevailing winds blow from west to east at these latitudes
It affects the Pacific Coast from Northern California to Southern Alaska, which includes British Colombia.
Winds are categorised according to the direction from which they blow - so a Northerly over NZ blows from the tropics towards the south and is usually a warmer air flow, while a southerly, blowing from Antarctica, would be chilly. Westerly winds over NZ are the prevailing winds, that is, they blow from that direction most often. Westerlies blow from Australia, across the Tasman Sea and approach NZ along its West Coast.
