On December 17, Typhoon Rey crossed the Philippine Archipelago, bringing stormy weather to many parts of the central Philippines, and Cebu, the second largest city in the Philippines, has experienced a large-scale power outage and completely paralyzed traffic. Despite the influence of the Philippine topography, Typhoon Rey has weakened in intensity, but at 20:00 on December 17, the Central Meteorological Observatory believes that it is still a strong typhoon level of 14, and has now crossed Palawan Island in the western part of the Philippine Archipelago and is entering the waters of Hainan, China.
The mountains of Palawan are generally not high, and the impact of Typhoon Rey over the island does not seem to be very large, and on the evening of December 17, satellite microwave scans showed that the internal structure of Typhoon Rey was actually relatively intact, the structure of the eye of the wind was still maintained, and the eye of the wind was leaving Palawan in its entirety, indicating that its core area was less affected by the terrain.
At the same time, the core convective area of Typhoon Rey is still very strong, from the infrared satellite cloud map, this evening is passing through the island of Palawan near the center of Typhoon Rey has a large area of strong cold cloud area with a cloud top temperature below -80 degrees Celsius, and near the core area is an area of genting temperature below -90 degrees Celsius, and some areas are even close to -100 degrees Celsius again. Genting temperature as the name suggests is the temperature of the top of the cloud layer, the typhoon itself is an updraft, a strong updraft can allow the clouds to develop to the upper troposphere of more than 10 kilometers above the ground, and the temperature of the troposphere decreases with the height rise, and the cloud temperature of the upper troposphere can drop to a particularly low level, which forms an extremely cold cloud top temperature.
For Typhoon Rey, the appearance of a cloud top temperature of -100 degrees Celsius means that the updraft activity inside it is still very strong, which is related to the particularly high seawater energy in the sea area where Typhoon Rey is located, and also related to the topographic and atmospheric conditions. In general, whether the eye structure is still there or the convection is strong, it means that Typhoon Rey still retains considerable intensity, and after entering the South China Sea, it will have a significant impact on the archipelago and shipping in the South China Sea.
The Central Meteorological Observatory even believes that after Typhoon Rey enters the South China Sea, it may also develop to a super typhoon level of 16 again, which may bring rare winds and storms to the islands in the South China Sea in the same period. However, from the forecast of the Central Meteorological Observatory, it can also be noted that Typhoon Rey will move north from the South China Sea from December 19, and may be very close to Hainan, Guangdong in the later period.
Although it is not certain whether it will land in China, many meteorological agencies have pointed out that the proximity of Typhoon Rey will bring rare wind and rain to the south China coast. For example, the Hong Kong Observatory on the south Coast of China has pointed out that it is more certain that the cloud belt associated with Rey will bring rain to the South China coast next week, which will be a fairly rare close wind and rain in mid-to-late December.
