Answer:
San Francisco is influenced by coastal upwelling and Dublin is influenced by the Gulf Stream
Explanation:
San Francisco and Dublin are cities that are located in the Northern Hemisphere, at similar latitudes, with Dublin being the one that is slightly more north. Despite them being influenced by different oceans, San Francisco by the Pacific Ocean, while Dublin by the Atlantic Ocean, they have very similar weather conditions. San Francisco is influenced by a coastal upwelling. This brings a lot of moisture, manifested through lot of clouds and precipitation throughout the year, also keeping the temperature mild and without any extremes. Dublin on the other side, is influenced by the Gulf Stream, which is a warm ocean current that brings in warm and moist air masses. That results in milder climate than what would be expected on that latitude, with lot of precipitation, and littlno to no extremes in the temperature.
