Will the cool hot this summer make the winter extremely cold?Can the last Fu be cooler?The answer is →

This summer, Shanghai continued to be high temperature. Although it has entered the "ending", it was still born on August 16th. The 43rd high temperature day (35 ° C and above) in Shanghai this summer was still born. History was rare.

In this hot summer, most areas across the country are also shrouded in high temperatures. High temperatures above 40 ° C continued to appear in many places, and long time, strong intensity, and wide range, many indicators refresh the meteorological records.

In June of this year, the global land regions appeared the hottest temperature since the end of the 1850s. Humanity records have swept the northern hemisphere in high temperature, drought, wildfire, heavy rain, and floods.

So, will 2022 the hottest year in history? Will the heat this summer make the winter extremely cold? Why is the body temperature and meteorological station report inconsistent with the measured temperature?

Will summer heat make the winter extremely cold?

Liang Ping, the chief of climate forecasting of the Shanghai Climate Center, told Jiefang Daily · Shangguan Journalists that from a scientific point of view, combined with local data of Shanghai, there was no significant correlation between hot summer and cold in winter. In the long run, whether it is summer or winter, there is a tendency to warmer, but different areas are different, some places are obvious, and some places are not obvious. However, in the context of global warming, extreme cold waves will not be ruled out in winter.

Can the last Fu be cooler?

Shanghai has entered the "ending" and has been 10 days from August 15. So, can the last Fu be cooler?

the answer is negative.

In the future, under the strong control of the high -pressure high -voltage of the subtropical tropical, the main tone of the hot and hot heat will remain unchanged. During the last period, high -temperature weather in Jianghuai, Jianghan, Jiangnan and other places, including Shanghai, will continue to continue, and the number of high temperatures is expected to reach 7 to 10 days. There will be a small cooling on August 17, but this is just a "episode". The temperature will rise again on the 18th. The extreme high temperature will appear again on the 19-20 days, and it is expected to reach about 40 ° C.

The reason is that on the one hand, the clear and cloudy sky cannot stop the enthusiastic sunlight, and more short -wave radiation is received on the ground. On the other hand, the temperature of the air sinks also causes the air to dry and warm, and the temperature rises.

Why is the temperature in Apple weather a lot higher?

Recently, many netizens have found that the temperature in Apple mobile phones comes with software is much higher than the temperature reported by the Meteorological Bureau.

On August 5th,@8 8 8 Reply netizens: "Because the weather forecast in Apple's own system is provided by TWC in the United States. For the part of the live temperature based on geographical location, they are not using the real temperature observed temperature. Instead, the live temperature that is estimated through other means. The temperature data provided in our service is the atmospheric base temperature measured by the standard meteorological observation station based on the unified technical standard. "

Where is the maximum temperature?

What can represent the highest temperature is the observation record of meteorological observation stations.

Even in the same city, different regions will be different due to different geographical conditions. Under the sun exposure, the ground temperature may break through 40 ° C early; the temperature of the water surface in the swimming pool will be lower; the temperature in the expeditionary valleys may be lower. In order to unify the standards, the World Meteorological Organization stipulates that the lower surface of the meteorological observation station requires a certain area of ​​Asakusa. The thermometer needs to be placed in the louvery box, and the shutters need to be 1.5 meters away from the ground. Essence

So the official authoritative data you see comes from the shutters on the lawn. This temperature will indeed be lower than the asphalt road, but the global unified standard is to facilitate scientific statistics. Only the global meteorological observation station has a unified standard to analyze the meteorological observation data obtained in the same environment, and then judge the movement speed and scope of the atmospheric system over the earth.

Shanghai Xujiahui Observation Station is located in the urban area. The highest temperature in summer and day is higher than that of the suburban meteorological observation station. At the same time, the Xujiahui Observation Station has continuous observation records since 1873, which is convenient to compare with long sequence history. Therefore, Xujiahui Observation is usually used. The highest temperature on the station represents the highest temperature in Shanghai.

Is it the hottest year in history in 2022?

Since June 1st to August 15th this summer, the average temperature in Shanghai is 29.8 ° C (Xujiahui Station), which is 2.4 ° C higher than the same period (average 1991-2020), breaking the record of the same period. From 2018 to 2021, due to typhoons, Meiyu and other factors, Shanghai extreme high temperatures appeared less.

Liang Ping said that the direct cause of extreme heat this summer is that the continuous stability of the subtropical high pressure affects the middle and lower reaches of the Yangtze River, which prevails to sink the air, which will cause the atmosphere to increase the temperature and manifest itself in a state of sunny and hot rain. Many places around the world are also affected by high -pressure bands. East Asia is the Western Pacific Auxiliary High pressure, North America is the high voltage of the Atlantic Ocean. In addition, there are Northern Africa-Iran's high pressure. Previously, these high-pressure systems were disconnected. This year, the global high-voltage belt was presented, which basically was connected together, and it continued to be stable. Therefore This summer, Europe and other places are very hot. The phenomenon of this extreme weather is a combination of various factors, including global atmospheric abnormalities and ocean.

According to a report released by the United National Disaster Prevention and Disaster Prevention and Restaurant, compared with the previous twenty years, the frequency of various disasters in the first two decades of the 21st century increased significantly, of which high -temperature incidents increased by 232%, and heavy rain increased by 134%. Each each, each, each, each, each, each. The storm increases by 97%, while China is the country with the largest number of climate disasters.
