The coast of Shandong was hit by typhoon "Namadu". How much impact did the typhoon have on the weather?
Shandong has recently been affected by Typhoon Nanmadou, with maximum gusts of level 10. Yes, in Shandong, the combined influence of typhoons and cold air will cause large to huge waves of 3 to 4 meters in offshore waters. The northerly winds in central Shandong and various sea areas are stronger and gradually weaken at night. So how much impact does the typhoon have on the weather?
When a typhoon comes, sometimes big trees will be uprooted, and even the roofs may be blown off by the wind, and accompanied by strong winds, there will be heavy rain, which will hit the city in a short period of time. A large amount of water pours from the ground, submerging dealers, destroying houses, even interrupting transportation, and forcing some factories to suspend production. However, typhoons on the sea are more dangerous than on the ground, setting off huge waves, threatening people sailing at sea. The life safety of ships and personnel engaged in fishing, farming, oil extraction and other operations. Typhoon is a kind of disastrous weather that can cause huge disasters to people.
Typhoons will usher in strong convective weather such as heavy rains or extremely heavy rains. Strong heavy rains in a short period of time can cause urban flooding, landslides, mudslides and other disasters. The strong winds brought by typhoons are one of the main hazards. They can cause falling objects, collapse of dangerous buildings and other easy accidents. They can also cause storm surges, causing the tide to overflow into the sea and destroy houses and various building facilities. , as well as flooding towns and farmland, causing a large number of casualties and property losses. Typhoons will not only bring strong winds and heavy rains, but also have an impact on traffic, causing a large-scale impact on road traffic, maritime vessels, aviation, etc. affected.
When the typhoon passes through, it is a sea area with dripping salt water and a strong carbon source. However, after the typhoon passes through, it becomes a sea area with high salt water and weak carbon sink, and the carbon dioxide flux increases. The upwelling caused by the typhoon brings seawater with low temperature, high salinity, high chlorophyll and rich in dissolved inorganic carbon from the subsurface layer to the surface layer, thereby increasing the partial pressure of carbon dioxide in the surface layer of seawater, forming a weak carbon atmosphere that will remain after the typhoon passes. Resulting in an increase in dissolved oxygen concentration in seawater. The phenomenon of low temperature, high salt and high chlorophyll appeared.
