Behind the highest temperature in Ningbo, there are these reasons behind you

"When can you retreat at high temperature?"

"Hey……"

Video production reporter Shi Chengcheng

From July 5th to July 13th, the high -temperature weather above 35 ° C in Ningbo has lasted for 9 days.

Since July 8th, Ningbo City has encountered "burning" with high temperatures above 38 ° C. Among them, on July 10, July 12, and July 13, the highest temperature in some areas reached above 40 ° C or above Essence

In the meantime, the highest temperature in each district (county, city) is "you chase me":

Haishu, 40.6 ° C; Jiangbei, 41.1 ° C; Zhenhai, 39.7 ° C; Beilun, 39.8 ° C; Lizhou, 40.3 ° C; Fenghua, 40.6 ° C; Yuyao, 41.6 ° C; Cixi, 40.2 ° C; Ninghai, 38.3 ° C; Xiangshan, 40.7 ° C.

It is worth mentioning that from July 8th to July 13th, high temperatures above 38 ° C in the urban area have appeared in the city for 6 consecutive days. most.

The longest high temperature time above 38 ° C is Yu Yao, with a cumulative 1367 minutes.

"When can you retreat at high temperature?"

Judging from the ten-day forecast released by the Municipal Meteorological Observatory on July 13, due to the influence of weak and cold air, the subtropical high-pressure forces weakened. The high temperature eased from July 16th to July 18th, and the highest temperature was 34 ° C-37 ° C.

However, starting from July 19, a new round of high temperature weather will come again.

More or less "seemingly saying, it seems like nothing".

"I want to ask the earth and ask the earth", why is this?

The sixth evaluation report of the Special Committee for Climate Change of the United Nations (IPCC) shows that global warming in the past 50 years has occurred at unprecedented speeds in the past 2000. This is the climate background that occurs in high temperature weather.

The current abnormal changes in the atmospheric circulation are the direct causes of high temperature weather and continuing.

In the first half of this year, the forces of the Western Pacific subtropical high -voltage were weaker than usual, and the main body has been lingering at the sea. Since July, after the typhoon "Siaba" go north, the Western Pacific subtropical high -pressure band extends west, Iran's high -pressure belt east, and with the east of the Iranian belt, and with the east of the Iranian belt, and with the east of the Iranian belt, and the same as The high -voltage combination of the mid -latitude continent has a stable heating high -voltage belt over my country.

In our city, it is just in the Western Pacific subtropical high -pressure west extension control area.

On the one hand, there are sinking air flow near the ridge line, and the temperature increases significantly. In addition, the sun is clear and the solar radiation is strong, so that the ground can absorb more short wave radiation of the solar.

On the other hand, due to the small air pressure gradient, weak wind, the weather is more sultry, and the body sensation is uncomfortable.

In addition, under the control of high -pressure spine in the Western Pacific Ocean, the atmosphere is humid, the energy is gathered, and the north side of the high -pressure spine is adjacent to the west wind zone.

When these systems penetrate, even if a little disturbance is brought, it will cause intense convective weather, accompanied by short -term rainstorms, thunderbolt, thunderstorms, etc., and even hail.

The weather is "high fever" without retreat, and even the river can not feel the coolness. Reporter Shi Chengcheng

In the past years, every "high fever" day has made people remember.

In the summer of 2007, the highest temperature of the daily daily temperature of ≥35 ° C was 46 days, of which 28 days were in July; from July 25th to August 3rd, the highest temperature in the urban area exceeded 38 ℃ exceeded 38 ℃ for 38 ℃. Essence

From July 1st to August 13th, 2013, severe high -temperature heat wave weather appeared in our city. The high temperature strength, long duration, and extensive influence, rare history.

The city's average temperature is 30.9 ° C, and the number of high temperatures above 35 ° C is 31.4 days. In addition to Ning overseas, the average temperature, high temperature daily, extreme maximum temperature and other meteorological elements have broken the record of the same period since Ningbo have meteorological records.

The number of high temperatures of each district (county, city) ≥38 ° C, ≥40 ℃, and ≥42 ° C greatly exceeds the extreme value since the meteorological records. Fenghua broke the city's highest temperature pole value record at 43.5 ° C; Ningbo Meteorological Observatory issued an unprecedented high -temperature red warning for 14 days.

Fenghua for 7 consecutive days ≥40 ℃ (the longest record of 4 days), for the first time for 5 days ≥42 ° C, and 4 consecutive heavenly ranked first in the country's highest highest.Yuyao for 7 consecutive days ≥40 ℃ (the longest record of 3 days), for the first time for 5 consecutive days ≥41 ° C.

The urban area has been ≥40 ° C for 6 consecutive days, and the most records have been created.

In the summer of 2017, the average number of high temperatures above 35 ° C in the city was 40.5 days, 22.8 days more than the same period of the year, second only to 2013 (42.8 days).

The high temperature span is long and concentrated, which is roughly divided into two concentration periods, from July 5th to July 29th and August 3rd to August 29th, respectively.

Among them, the high temperature intensity in July is stronger and the continuity is better.From July 18th to July 26th, strong high temperature weather above 38 ° C appeared in our city, with a maximum of 39 ° C -40 ° C in some areas and a maximum Yuyao 40.8 ° C.
