On the tail in September

We are all looking forward to autumn

I didn't expect to welcome the midsummer

Advant tropical high pressure enhancement

High temperature coming and aggressive

From the end of September to the beginning of October, the subtropical high pressure will be lifted north, and the high temperature in the south has been strengthened again. The intensity is comparable to the midsummer season!

The subtropical high -pressure enhancement, cold air slackness. Until the early days of the National Day holiday, Zhejiang felt like a midsummer during the day, named Luzhou, Jinhua, Lishui, and the "big furnace" was still burning until early October, even 38 ° C+still waiting.

High temperatures occur in September, which is still more common in history. Judging from the later high temperature forecasts, in the early stage of the National Day holiday, our province may have large -scale high temperature weather, and many places may break the highest temperature record in the local October, which is quite rare!

The latest high temperature daily record in Hangzhou appeared on October 2, 1984 (up to 35 ° C). On October 3 last year, the highest temperature reached 34.4 ° C, which was only one step away from the break.

In the early stage of the National Day holiday this year, under the control of the deputy high, the high temperature came fiercely. Looking at this posture, this year is likely to break this record!

Let's go back to summer first, and then "autumn one night"

This holiday Zhejiang weather is too exciting

However, the outrageous autumn tiger, but also cold air! In the second half of the holiday, the cold air will go south, and the weather will change sharply, and the cooling, rainfall and wind will be indispensable.

The hotness is close to the midsummer first, and then "overnight autumn", the extent is more intense like the deputy high of July to August meet the cold air from November to December. How many months.

In the past two days, there are many cloud systems, especially after noon, the thick clouds cover the sun, and light rain floats in some areas. Raising the temperature is also suppressed, do you feel very comfortable?

The cool and comfortable weather is only one day today. Tomorrow, with the high -pressure control of the auxiliary tropical, the weather will officially open!

Continuous high temperature

Is the osmanthus is late?

Together with the late autumn, there are osmanthus with the hearts of Hangzhou people.

This year, there is no fragrance of osmanthus, is it be late?

According to the analysis of Zhejiang Meteorological Expert Lou Maoyuan, this year, since our province has experienced the most weather records, the highest temperature has been in Hangzhou. As far as Hangzhou is concerned, the number of days with a continuous high temperature of 35 ° C has reached 54 days. Too meteorological drought is not good for the growth of osmanthus.

After a whole summer, the flower buds of osmanthus are still dormant, and the temperature will not be reduced to a certain extent until the autumn.

The early cinnamon is generally opened to September, and the average temperature of the sliding for 10 consecutive days is <26 ° C, and the lowest temperature during the period is <24 ° C.

Late laurels generally open to October in the late September, with an average temperature of 10 consecutive days <23 ° C, and the lowest temperature during the period is <20 ° C.

"If you want to be full of osmanthus fragrance, you must bloom late." And the recent temperature will not meet this condition.

Osmanthus is a plant that is very sensitive to autumn temperatures. In addition to temperature, it is also closely related to humidity. Precipitation is an important part of nutrient transportation during plant growth. If Comparison drought, then it is not conducive to the growth of osmanthus buds. Since July this year, the average precipitation of the province is 269 mm, 45%less than the same period of the year. On the eve of the National Day, most parts of our province are mainly cloudy weather, and the possibility of temperature falling below 23 ° C is relatively small.

Therefore, experts predict that this year, the large -scale flowering of osmanthus will be late. It is estimated that it will be full of fragrance from the middle of October or even late October.

In other words, this year's autumn and osmanthus are also a bit late.
