Autumn typhoons usually refer to typhoons generated from September to November.
Regarding this big brother in the weather world, how many of the following "true" and "fake" can you tell the following "
"? Let’s take a look at
!
1. More typhoons in autumn?
fake!
According to meteorological data statistics from 1981 to 2010,
generates an average of 10.9 typhoons in autumn, and
has 2.5 typhoons landing in my country every year, second only to summer. In terms of
, the summer typhoon won a small game.

2. Is super typhoon more likely to appear in autumn?
really!
According to statistics from the Japan Meteorological Agency, between 1951 and 2010, among the top 20 typhoons with the lowest air pressure (usually the lower the air pressure, the stronger the intensity),
autumn typhoon occupied 13 seats, reaching 65%, and
summer typhoon occupied 6 seats, accounting for 30%.
shows that the overall strength of the autumn typhoon is stronger.

The reason why super typhoons are more likely to occur in autumn is
mainly because when summer transitions to autumn, the direct sunlight point moves from north to south, causing the sea temperature to be warmer.
High sea temperature means more heat is accumulated and the energy provided to the typhoon is also greater.
is therefore more likely to have stronger typhoons.
3. Is the autumn typhoon more "happy" to land in Guangdong and Hainan?
really!
Compared with summer typhoons, the landing location of autumn typhoons is more southerly.
is mainly concentrated in the areas south of Zhejiang, and
has the easiest provinces to log in to are Guangdong and Hainan.
This is because after the autumn enters, the subtropical high pressure that affects the tropical cyclone path begins to retreat eastward and southward, and the
position gradually goes southward.

4. Is the "emotion" of autumn typhoons more stable?
fake!
The meteorological factors affecting my country's offshore typhoons are mainly weather systems of
westerly wind belt , subtropical high pressure, equatorial convergence zone and other weather systems.
In autumn, these forces are in a game state and cannot decide on a clear victory or defeat.
None of the forces of all parties occupy a strong position, so
has caused the typhoon to be affected by various factors, and the movement path and intensity of
are also prone to change.
Especially after entering the South China Sea, the complex terrain will make the path of autumn typhoons
and intensity changes appear more complex characteristics.
2015 Typhoon "Rainbow" No. 22, 2015, was generated on Luzon Island, Philippines in the early morning of October 2, and landed on the coast of Potou District, Zhanjiang City, Guangdong Province around 14:10 on the 4th. The "Rainbow" is the strongest typhoon to land in Guangdong in October since meteorological records, and it is also the strongest typhoon to enter the inland Guangxi in October. The strong storms and rainstorms brought by it are superimposed on astronomical tides, tornadoes and heavy rainfalls and other disasters caused by mudslides and landslides.

5. I heard that it is the sea water that "supports" the autumn typhoon?
really!
Typhoon generation and development requires warm seawater to provide energy.
usually has the highest sea temperature from August to September, so typhoons are the most active at this time.
, especially in autumn, a lot of calories has been accumulated.
is like a prize pool that has not drawn many times in a row.
is often prone to generate a huge prize.

6. The autumn typhoon can offset it when it encounters cold air, "negative negative is positive"?
fake!
is just the opposite. Cold air is active in autumn.
If a typhoon encounters cold air, it can stimulate stronger precipitation.
has accomplice of cold air, which will lead to greater disasters.

On September 15, 2016, after typhoon "Moranti" landed on Xiamen , a severe rain occurred in Jiangsu and Zhejiang areas located at the trough of its typhoon, which caused a landslide mudslide disaster in Suichang, Zhejiang.

It can be seen that the autumn typhoon is a powerful character.
's destructive power cannot be underestimated, and
cannot relax and prevent it because there are few logins.
In addition, autumn typhoons will also cause serious harm to my country's agricultural production.
9-October is the maturity period for the late rice ears and flowers in southern China.
If a typhoon strikes at this time,
will cause serious production cuts or even deadlines.
Therefore, the impact of autumn typhoons on agriculture also needs more attention.

Important tips:
Central Meteorological Observatory Latest news,
Typhoon No. 16 this year "Mawa" was generated at 2 am on September 1st.
(tropical storm level, English name: Mawar; name source: Malaysia ; name meaning: rose)
Central Meteorological Observatory issued a blue typhoon warning this morning.
is expected to land on along the coast of in central Guangdong during the day on September 3. The intensity of
when logging in is strong tropical storm level or typhoon level (30~38 meters/second, 11~13 levels).
meteorological experts remind that the impact of
typhoon "Mawa" on land will start from the night of the 2nd and will be the strongest on the 3rd.
There will be strong wind and rainy weather in most areas of Guangdong, southeastern Fujian and other places, with heavy torrential rainfall generally, and local heavy rainstorms, and instantaneous wind will be above level 10.
This is also the third typhoon that
has encountered in Guangdong in half a month since late August this year.
It should be noted that Guangdong has been hit by typhoons in a short period of time, and some areas with severe typhoon disasters have not yet returned to normal. Therefore, the public should pay attention to taking typhoon prevention measures, and avoid entering dangerous areas such as mountainous areas, river valleys and low-lying areas.
Local friends, be careful~!
