An extreme heat wave of 47.9 degrees swept across North America. This week, as one city after another broke the record of the highest temperature in history, the adverse effects of drought are intensifying. The intensity of this heat wave is unprecedented since mankind entered the modern society. Up to now, about 250 people in the United States and Canada have lost their lives due to high temperatures.

47.9 degree extreme heat wave sweeps across North America 1 Last weekend, an unprecedented dangerous heat wave swept across the west coast of North America.

The strengthening of high-pressure air masses centered on the Pacific Northwest and southwestern Canada has caused the temperature to soar, and the US National Weather Service warned that the temperature may reach a record high.

This week, as one city after another broke the record of the highest temperature in history, the adverse effects of drought are intensifying.

0 1 this heat wave "once in a thousand years"

CBS reported that the intensity of this heat wave is unprecedented since mankind entered modern society. In a sense, such a heat wave is once in a thousand years-that is, staying here 1000 years.

Jeff Berardelli, a meteorologist of CBS, calculated that "only the probability of110000" can form such a large-scale "heat wave" in this area.

According to the probability density function of normal distribution, the current high temperature intensity deviates from the average value by more than 4.4 standard deviations, indicating that the probability is about110000.

More than 02 cities recorded high temperatures.

In Oregon, the temperature in Portland reached a record high of 4 1.7 degrees Celsius for three consecutive days, while Eugene (43.8 degrees) and Salem (45 degrees) both reached record highs.

Vancouver, Washington (44.4 degrees) and Seattle (40 degrees) also set records.

Extreme high temperatures also occurred in Canada, and Litton, British Columbia, broke the high temperature record for three consecutive days, reaching 49.5 degrees Celsius.

03 public facilities were "burned out"

On Sunday, the tram in Portland was forced to suspend bus service, and the power cord of the tram melted due to the high temperature.

In everson, Washington, photos shared by local officials show that some roads have large cracks.

In Yakima County, Washington, pictures uploaded by Twitter users show that sidewalks have even become arched.

Millions of families have no air conditioning.

Take Seattle as an example. Because it is a temperate maritime climate, it faces the cold sea breeze of the Pacific Ocean all the year round. Generally, it rarely exceeds 30 degrees in the afternoon in summer, 18 degrees in the evening, and occasionally the high temperature lasts for up to one day. So ordinary people don't install air conditioning.

According to Bloomberg statistics, only 44.3% of Seattle families have installed air conditioners, and most people are unprepared for this extreme heat.

In many shops in Portland and Seattle, fans and air-conditioning equipment were snapped up, and many residents had to find ways to seek air-conditioning "shelter".

According to BuzzFeed, hundreds of people took refuge in air-conditioned libraries, shopping malls, cinemas and other officially designated "cooling centers". The booking volume of central air-conditioned hotels has also increased significantly.

People rest in the "cooling center" of the Oregon Convention Center.

A resident of Seattle told AccuWeather that he even fell in love with his job in order to get air conditioning.

Extreme heat wave of 47.9 degrees swept across North America. At the end of June, rare high temperature weather appeared on the Pacific coast of the North American continent. On June 30th, a record high temperature of 49.6℃ occurred in British Columbia, Canada. Up to now, about 250 people in the United States and Canada have died of high temperature, most of whom are elderly people.

According to foreign media reports, the Canadian environmental department said that on June 28th, local time, the highest temperature recorded in British Columbia was 47.5℃. The video posted by netizens on social media showed that firefighters used fire hydrants to cool down local people and animals.

It is reported that in these two days, Vancouver police in Canada received at least 65 reports of sudden death. The death caused by high temperature takes up almost all the first-line resources and delays the reaction time. The police station said that dozens of policemen had been deployed to stand by and asked the public to call 9 1 1 only in an emergency.

At present, the heat wave continues to affect many cities in Canada and the United States, and the death toll may rise further. The police appealed to residents to take corresponding preventive measures.
