Difference in temperature exceeds 25 ℃ ! Shandong " is glacial fire double day " ? Atmosphere expe

Chinese atmosphere signs up for reporter Wang Meili

On June 4, one went up with the news that air temperature concerns " hot search " . Netizen discovery, shandong is saved western highest air temperature exceeds bureau ground 40 ℃ , and air temperature of a few areas is not worth the eastpart part 20 ℃ , afternoon 3 when the left and right sides, the biggest difference in temperature amounts to thing ministry 25.2 ℃ , the netizen speaks: "At the same time Sahala, at the same time pole of north and south! " so, why to save in, can same hour appear so big difference in temperature?

Picture origin: Shandong saves observatory

Different weather system and difference of underlay face attribute bring up difference of air temperature of Shandong thing ministry 25 ℃

Presiding forecast Yuan Chentao explains central observatory, main reason has two, because Shandong the eastpart part suffers cold eddy 4 days day,be hind cold air is affected, air temperature relatively compare before today drop apparently. For instance 4 days of 14 air temperature of Shandong Yantai when and photograph of air temperature of 13 days of same hour are compared, reduced 12 ℃ . And the weather system that affects hill thing department basically is backbone of warm sex high pressure, in its control falls, be current sinks air current, fine heat is partly cloudy afternoon, temperature is elevatory very fast, accordingly, local air temperature is highest developed 40 ℃ above.

The 2nd reason is, mix littoral difference of attribute of face of inland area underlay is apparent. Shandong peninsula foreland is affected by deep-sea, summertime itself weather is met Bixibunei land is a few cooler; Face of inland and general underlay basically is the each type soil such as farm, thermal capacity is relatively lesser, the radiate below the case that there is sunshine afternoon warms up apparent. Accordingly, the difference of feature of underlay face attribute also can cause Shandong to have certain difference with inland area temperature littoral.

What need points out is, if Shandong complete province suffers effect of even weather system, because underlay face attribute is different, the summer usually, also can form the difference in temperature of 4~8 ℃ with inland littoral. Can cause 25 ℃ such difference in temperature, besides underlay face attribute, analyse the effect that different weather system causes even.

Finally, sum up, the factor that affects summertime difference in temperature has 3:

Weather system. Below control of different weather system, temperature expression is very different, general cold sex air mass is controlled (like cold eddy, sharp edge hind cold high pressure) below, air temperature will be lower; And in warm sex air mass (be like high-pressured backbone, mainland high pressure, subtropic high pressure) below control, especially the summer, with respect to weather of high temperature of ground of meeting occurrence bureau.

Underlay face feature. Marine effect suffers around foreland, the contrast of day change photograph of temperature is evener, opposite afternoon below influence of sea land wind meet at inland area a few cooler; And be far from deep-sea inland area, thermal capacity of underlay face soil wants than ocean a lot of smaller, warm up afternoon so the meeting is very quick, weather of easy generation high temperature.

Landform. Need not difference of air temperature of height above sea level is apparent also, below average position, every differ 100 meters, with respect to the difference in temperature that can 0.6 ℃ are controlled, if difference of two ground height above sea level 1000 meters, can have the air temperature difference that 6 ℃ control so. This is why the account with high mountain downy or smaller air temperature.
