Canada and the Pacific Northwest are currently groaning under the heat of a millennium. with the coastal states of Washington; In Oregon and British Columbia, temperatures are often above 37 degrees. The extreme weather is likely to continue till mid-week. Then the continental heat formation changes According to media reports East Side.
Together Official 46.6 °C A temperature record was set for Canada on Sunday. The value recorded in Lytton, British Columbia is markedly higher than the previous record of 45 degrees from 1937. Today, Monday or Tuesday, for which meteorologists had even predicted 47 degrees, the small town could again break its own record.
The trigger for extreme weather is the jet stream, a band of westerly winds that circle the Arctic at high altitudes and thus affect the movement of areas of high and low pressure. Over North America, this wind current has recently expanded significantly northward, allowing warmer air from the south to enter the north. Experts refer to the “omega position” after the similarity of the wind pattern to the Greek letter. This loop barely moves from the spot, it becomes blocked, causing the hot air to turn in a circle and thus continue to heat up.
The record-holding city of Litton has an average maximum daily temperature of 24.3 degrees. Statistically speaking, depending on the climate of the past, such a large summer bell should come only once every few millennia or ten thousand years. However, the climate of the past no longer holds as well in North America. Due to climate change, it has already warmed by about a degree on the northwest coast. In addition, experts consider the possibility that climate change will encourage the jet stream to rotate. The bulges, which remain constant for weeks, are more likely to be the temperature contrast between southern latitudes and the Arctic. The Arctic, in particular, has warmed significantly faster than the rest of the planet in recent decades.
A wave-pulling jet stream recently gave central Europe a humid spring and western Siberia a record summer. In May, the weather stations in the Arctic Circle recorded a temperature of around 30 degrees Celsius.
