Has Shantou typhoon been lifted?
Shantou city was affected by the typhoon, which brought a lot of trouble to the local people. Fortunately, with the joint efforts of the local people, the typhoon has been lifted. According to the regulations of the meteorological department, when the typhoon center has been far away from the dangerous area and the wind has weakened to a certain intensity, the typhoon warning can be lifted. At the same time, other factors such as weather and hydrology need to be considered to ensure safety.
In the process of lifting the typhoon, the meteorological department issued an alarm in time to remind people to take preventive measures. The local government has also taken active measures, such as organizing rescue teams and providing shelters to ensure the safety of the people.
After the typhoon is lifted, people need to do the aftermath. First of all, we should clean up the site, sort out the items that have been blown down by the wind, and repair the damaged buildings and facilities. Secondly, it is necessary to pay attention to hygiene and food hygiene to avoid diseases caused by food and water pollution caused by typhoons. In addition, we need to pay attention to safety issues to avoid accidental injuries caused by wires and trees.
Causes of typhoon in Shantou:
1, tropical ocean
Tropical ocean is the main energy source for the formation and development of typhoons. In the tropical ocean, seawater can absorb a lot of solar radiation, and the temperature of seawater rises, forming a huge water vapor pressure, which drives the formation and enhancement of typhoons. So whenever there is a tropical disturbance in the tropical ocean, it may develop into a typhoon.
2. Suitable climatic conditions
Under the influence of seasonality and climate change, the sea surface temperature rises and the water vapor content in the atmosphere increases, which provides favorable conditions for the formation of typhoons. In addition, the wind field in the atmosphere is also one of the important factors affecting the formation of typhoons. When the wind field is conducive to the convergence and rotation of airflow, it is possible to form a typhoon.
For Shantou City, due to its geographical location in subtropical coastal areas, high temperature and high humidity in summer, this climatic condition is conducive to the generation and development of typhoons. When typhoons pass by, Shantou city is often affected by strong winds, heavy rains and storm surges brought by typhoons, which may threaten the lives and property safety of local people.
3. Global climate change
With the intensification of climate change, the sea surface temperature rises and the water vapor content in the atmosphere increases, which provides more favorable conditions for the formation of typhoons. At the same time, climate change has also led to the increase of extreme weather such as rainstorm, flood and drought, which also makes the impact of typhoon more complicated and serious.
