typhoons have really been very busy since september this year.

↑take a little test, can you find all the typhoons?

generated on september 1typhoon no. 11 "makar"it made landfall four times in succession and was the strongest autumn typhoon to hit my country since meteorological records began. it maintained the super typhoon level for 64 hours, bringing widespread strong winds and rainstorms to southern south china, causing serious disaster impacts. the duration and impact range of the strong winds exceeded those of typhoon "wilma" in 2014.

just two days after the suspension of the "capricorn", on september 10,typhoon no. 13 "bebejia"it has become the first strong typhoon to land in shanghai since 1949, and also the strongest typhoon to land in shanghai since 1949. after landing, it will cross shanghai, jiangsu and anhui with wind and rain, and go deep into the inland, and will enter henan tonight. it is expected that there will be moderate to heavy rain in central and northern henan tomorrow, with local heavy rain and torrential rain.

typhoon no. 14 "prasang"it was formed on september 15 and is expected to land on the coast of zhejiang province (strong tropical storm level) in the afternoon or evening of the 19th.

typhoon soulik no. 15there is a tropical disturbance near the philippines. it has moved into the eastern waters of the south china sea this afternoon. its speed has slowed down and its intensity has gradually increased. it will develop into typhoon soulik no. 15 within 24 hours. it will approach the southern waters of hainan island and head toward the northern coast of vietnam in the future.

looking at the itineraries of these typhoons, there is basically one per week, and they are fully scheduled until the week before national day.

what’s worse is that these typhoons are not easy to deal with.

not only are there two record-breaking typhoons, "makar" and "bebejia", but "prasang" and the future "soulik" are also not easy to deal with.

from the perspective of its path, typhoon prasang no. 14 is going to follow the path of bebejia and head straight to east china, and may land in zhejiang. the day after tomorrow, the impact of bebejia will basically end, and prasang will begin to affect the coastal areas of east china, causing heavy rain and torrential rain.

typhoon soulik will approach the southern sea of ​​hainan island in the future. in the later period, due to the combination with cold air, even if it passes near the coast, the impact of wind and rain cannot be underestimated. it should be noted that the huge impact of "makar" on hainan has not been completely eliminated. for example, yesterday, a hainan netizen said that the power outage here due to "makar" has not been restored.

whether it is east china or south china, having just experienced the strong winds and heavy rains of the previous typhoon, and being hit by a new typhoon again in a short period of time, the risk of disasters is more likely to increase.

especiallyduring the influence of "prasang" and the future "soulik", we must also be alert to the possibility that the typhoon may combine with the cold air moving south to produce heavier rainfall.

xin xin, chief meteorological analyst at china weather net, said that in the later part of this week, cold air from the north will move southward. if typhoons "prasang" and "soulik" make landfall and penetrate deep into the area, they may combine with the cold air to cause significant rainfall.

in particular, the path of "prasang" will be very variable, and the rainfall in zhejiang, southern anhui, northern jiangxi, eastern hubei and other places in the later period will be highly variable. if it lands and penetrates deep into the area, we should be alert to the combination of the residual low vortex of the typhoon and the cold air to form heavy rainfall; but if the typhoon adjusts its path, turns southwest or turns northeast, the rainfall in the inland area will be significantly weakened.

the impact of the upcoming typhoon soulik on rainfall in south china is more clear. according to the current situation forecast, it will pass by the southern coast of hainan island or land on hainan island in the future. although it is weaker than the previous typhoon makar, due to the involvement of cold air from the north, rainfall in south china may exceed expectations, so we need to be highly vigilant. in addition, we must also be vigilant about the possibility of tornadoes in guangdong, guangxi and hainan under the triggering of cold air.

it can be said thatthis strong cold air, which will help enhance the typhoon's rainfall capacity, is an important factor affecting my country's weather in the future.

starting from the 19th, the cold air will first affect the north. from the 19th to the 21st, affected by the strong cold air, there will be northerly winds of 4 to 6 in the middle and lower reaches of the yangtze river and its northern areas. gusts may reach 7 to 8 in some areas. the temperature in most areas of central and eastern china will drop by 4 to 8°c, among which the temperature in parts of central inner mongolia, northern shaanxi, northern shanxi, northern hebei and other places will drop by 10 to 14°c.

the cold air will push the north into full autumn.during its influence period, which coincides with the beginning of autumn and the night of the white dew and autumnal equinox, it will get colder each night. the lowest temperature in the eastern part of northwest china, north china, and most of northeast china is only around 10°c. the autumn chill will be severe, so you should remember to add clothes to keep warm.

afterwards, the dry and cold north wind will continue to move southward. because of its strong strength, its impact will extend deep into southern china. in addition to assisting the typhoon,cold airit will also drive away the autumn tiger that has been entrenched in the south for a long time.not only is the high temperature in chongqing expected to stop, but the middle and lower reaches of the yangtze river will also become dry and cool from the previous sultry weather. although it is still a long way to the beginning of autumn, our friends in the south can finally experience the coolness of autumn!
