Recent The temperature of this abnormal seawater may bring serious consequences to the area.

It can be seen from the seawater temperature monitoring data on August 9th that the North Atlantic Ocean can be described as “hot waves”. From the Caribbean Sea to the Gulf of Mexico and the North Atlantic region east of Florida, the seawater temperature area of more than 30 degrees has appeared. In particular, the waters of the Gulf of Mexico and the Caribbean Sea have a large -scale white area: that is, the “high temperature seas” that generally exceed 32 degrees of water temperature.
For example, Florida in southeast of the United States, the monitoring data of the local site show that the water temperature of multiple sites on the east coast of Florida and the west coast is generally above 30 degrees, especially the west coast and the offshore of the southwest. The water temperature of multiple stations exceeds 33 degrees It can be said that it is surprising.
According to data from NOAA, the water temperature of the Gulf of Mexico south of the United States exceeds 32 degrees Celsius, which is the result of the common effect of various factors. First of all, this year is a strong El Nino year, which means that the temperature in the seawater in the Pacific equatorial area is about 2 degrees Celsius higher than that of the normal year. This will lead to changes in wind direction near the equator, thereby promoting the influence of more tropical air heating in the south of the United States, so that the temperature of the seawater is increased and accumulated in the Gulf of Mexico. Secondly, this summer is not affected by strong wind cutting and cold air balls in the south of the United States. These factors usually reduce the temperature of the seawater. Third, this summer, the southern United States has received strong solar radiation and frequent high temperature weather, which will also increase seawater temperature.
Second, global ocean may there be disaster?
From a greater perspective, the increase in seawater temperature in the Gulf of Mexico and even the entire North Atlantic area has more complex climatic factors. For example, the impact of global warming. Global warming leads to increased greenhouse gas in the atmosphere, causing the surface of the earth to absorb more solar energy, and the ocean is the largest heat storage library on the earth’s surface. When the ocean absorbs too much heat, it will cause the seawater temperature to rise.
In addition to global warming, there are also some natural factors that will also affect the temperature of the seawater. In addition to the well -known El Nino phenomenon, such as the Atlantic Meridional Mode, AMM) It affects seawater movement and affects seawater temperature in different regions. This shows that there are abnormal situations in the North Atlantic and the global circulation, which may cause extreme weather.
What are the consequences of high -temperature seawater?
As far as the North Atlantic and Mexico Gulf is concerned, high -temperature seawater is a huge threat to the area, because meteorologists point out that it may cause the following consequences:
-Anostic hurricane. Hurricane is a strong rotating storm that requires enough heat and humidity to form and maintain. Hurricanes may occur when the temperature of the seawater exceeds 26.5 degrees Celsius. When the temperature of the seawater reaches 32 degrees Celsius, it is possible to produce a super high hurricane, that is, a powerful hurricane at the fourth to fifth level. This hurricane has extremely high wind speed, rainfall and storm tide, which can bring more than 17 levels of wind and 10 meters above 10 meters, which can cause huge damage and casualties. For example, in 2022, the powerful hurricane Iian hit the United States Florida. According to NOAA’s forecast, this year’s Hurricane Season will be an active season, and there may be 15 to 21 named storms, of which 7 to 10 will become hurricanes, of which 3 to 5 will become super high hurricanes. This is for the United States and the United States and the United States and the United States and Many countries around the Gulf of Mexico are a severe challenge.
-Coral alternatement. Coral bleaching means that coral loses algae that is symbiotic because of environmental pressure, which leads to the phenomenon of coral white, loss of nutrition and death. The rise in seawater temperature is one of the main reasons for coral bleaching, because high temperatures can cause toxic oxides to produce poisonous oxides, which causes corals to reject algae. Coral albinization is a fatal blow for the marine ecosystem, because coral is the most important biological architect in the ocean. They can provide countless creatures in shelter, food and nutrition to the ocean. Moreover, corals also have important value to humans, which can protect the coastal line from storm erosion, provide tourism income and drug resources. According to NOAA reports, coral reefs in parts of the North Atlantic areas have suffered a serious albinization phenomenon, and some places even reached more than 90%of the albinization rate, which is a huge loss for the diversity of marine life in the area.
-Oero heat waves. Ocean heat wave refers to the phenomenon of abnormally increased seawater temperature and lasting for a period of time, which can affect the physics, chemistry and biological processes in the ocean. Ocean heat waves can cause increased seawater evaporation, increased salinity, decreased oxygen -soluble, changes in nutrient flow, etc. These will affect biological activities and distribution in the ocean. Marine heat waves can also lead to some harmful creatures, such as poisonous algae, jellyfish and fish parasites, which will threaten marine ecosystems and human health. According to NOAA reports, many marine heat waves have appeared in the North Atlantic Ocean, some of which lasted for several months, and even the highest level of 5 -level marine heat waves appeared, which is a serious Threat.
In addition to the Gulf of Mexico, some meteorologists have pointed out that this summer, the sea water temperature of the Mediterranean belonging to the North Atlantic region is unprecedented -British meteorologicalist Scott Duncan said that in late July, the sea water in the Mediterranean Sea The temperature completely exceeded all the previous records, and never measured the calories of the sea water in the entire Mediterranean area at any time.
Meteorologists call on governments and people to be alert to these issues, and take effective measures to reduce greenhouse gas emissions and reduce the speed and degree of global warming. At the same time, it is necessary to strengthen early warning and rescue capabilities to deal with natural disasters such as hurricanes to protect the safety of people’s lives and property.
