![]() Seattle in Winter is walled off from the East by the High Cascades. Vancouver gets more rainfall than Seattle simply because of its North Shore Mountains, which force the air upwards vertiginously, causing a heavier, more bursting rain than the lighter drizzle of Seattle. Vancouver and Seattle both are influenced in summer by the Eastern Pacific High Pressure Cell, which is more intense, and keeps both cities drier in summer.Ĭonversely, in winter, they both get a string of low pressure systems, bringing rainstorm after rainstorm. One of the biggest factors influeuncing the climate of London is that the summer High Pressure Zone (the Azores High Pressure Cell) is less marked, pressures are lower (and the air therefore contains more water) and London in summer can be quite cloudy, with spotty drizzle, although the city gets only 25 inches of rain per year. In fact, London receives considerably LESS rainfall than either Vancouver OR Seattle. ![]() Instead, forecasters expect a slightly above-average number of storms.Every day I open and I see in London the rain is much heavier and doesn't stop. As a result, this year's hurricane forecast isn't the quiet one you might expect for an El Niño year. The water in the Atlantic is very warm because of climate disruption, and warm water helps hurricanes grow. ![]() Generally, there are fewer storms during El Niño years, because wind conditions are bad for hurricane development.īut, even there, human-caused climate change is making itself felt. residents? El Niño is not good for Atlantic hurricanes. That's bad news for communities where flash floods have destroyed homes and even killed people in recent years, and where drain pipes and stormwater infrastructure is not built to handle the enormous amounts of rain that now regularly fall in short periods of time. In the Southern U.S., where climate change is making dangerously heavy rain storms more common, El Niño adds even more juice. That's bad news for Canada, which already had an abnormally hot Spring, and is grappling with widespread wildfires from Alberta all the way to the Maritimes in the East. In the Northern United States and Canada, El Niño generally brings drier, warmer weather. Here's what that means for weather in the U.S.Įl Niño also exacerbates other effects of climate change. That's how powerful human-caused warming is: it blows Earth's natural temperature variability out of the water. It's one of the most obvious ways that El Niño, which is a natural climate pattern, exacerbates the effects of climate change, which is caused by humans burning fossil fuels and releasing greenhouse gasses into the atmosphere.īut temperature superlatives obscure the bigger trend: the last 8 years were the hottest ever recorded, despite a persistent La Niña that took hold in late 2020 and only just ended, depressing global temperatures. The hottest years on record tend to happen during El Niño. " could lead to new records for temperatures," says Michelle L'Heureux, a climate scientist at the National Oceanic and Atmospheric Administration's Climate Prediction Center. ![]() The natural climate phenomenon is marked by warmer ocean temperatures in the equatorial Pacific, which drives hotter weather around the world. El Niño makes a record-breaking average annual temperature for Earth more likely.Įl Niño is officially here, and that means things are about to get even hotter.
