Why is Autumn Typhoon Harsher? "The Dangerous Combination of Cold Air and Typhoon"
9-11th Autumn Typhoon Intensity is not weak at Summer, the path is more bizarre, and once combined with the cold air of S, the storm will multiply Zoom in, Rammasun, Krathon are all Autumn Typhoon .
Typhon at the End of Strength.
Many people think that the typhoon season is summer, but in fact, the typhoon after September is often more dangerous:
- According to statistics, Super Typhoon in the autumn.At the end of summer and early autumn, the ocean has been heated throughout the summer, the sea temperature reaches the peak of the year, and the energy reserves are most sufficient.
- In 2014 Rammasun (mid-September), Mangkhut (September), Meranti (September), Haiyan (October) and Krathon (October) are all from late summer and autumn.
Three dangerous characteristics of typhoon
1 Change of path
Autumn sub-tropical high-pressure E retreat S retreat, W wind belt S pressure, guiding airflow complex and variable, typhoon trackForecast difficulty is the highest throughout the year.
Cold air" aid for malaria"
The most unique threat of Fall Typhon is associated with S’s undercold air:
- Cold air cuts in from Typhoon’s outer edge, and air pressure gradually increases. The wind range doubled.——Typhoon is still a few hundred kilometers away, and the coastal is winding.
- Cold air convergence triggers extreme precipitation, rainfall far exceeds Typhoon alone
- Typical such as 2013 Fitow: Landfall is only the lower limit of the Severe Typhoon, but in combination with the cold air left Yao's entire city flooded.
Sea temperatures decline but" inertia" remains
In the autumn near-sea temperature drops, the Typhoon Landfall will weaken before, but the peak intensity decrease takes time—to complete the"climb".
Defense points
- Don’t be vigilant because it’s all October while relaxing, Hainan, China’s Typhoon season lasts until 11-12
- The typhoon early warning window may be short (path mutation), and coastal residents should react immediately to orange above early warning
- Attention "Cold Air + Typhoon " Combination Forecast, The impact of winds in this situation is very large at Wind Circle Radius
