In the past two days, when the western Pacific Ocean opened the "typhoon assembly line" to produce typhoons one after another, the eastern and northern Atlantic Oceans in the western hemisphere were not calm - hurricanes were formed one after another in the North Atlantic and eastern Pacific, especially in the North Atlantic, where sea temperatures have been abnormally high this year, resulting in the formation of powerful Hurricane Idalia and hitting Florida with winds of more than 200 kilometers per hour.
One or two super-powerful hurricanes surround the United States
In fact, after the last wave of hurricanes, the current round of hurricane activity has begun again. On the afternoon of September 6, local time, from the high-definition visible satellite cloud image, there was a strong spiral-shaped storm system activity in North America, one west and one east. To the east in the North Atlantic is the recent formation of Hurricane Lee, the 12th named hurricane of the year in the North Atlantic. In the western and eastern Pacific Oceans, Hurricane Jova is raging and intensifying in the region.
Since the afternoon of September 6, local time, Hurricane Joya in the eastern Pacific Ocean has ushered in a rapid outbreak, with a small eye of wind with excellent clearance and a full central dense cloud area before nightfall, which shows the strong strength of Hurricane Joya. At present, the US National Hurricane Center (NHC) has given Jova 140 knots / h intensity, which is equivalent to a wind speed of 72 meters per second, equivalent to a continental-standard super typhoon, according to the Safir Simpson wind scale, it reaches the highest level of Category 5 hurricane intensity, and Jova is likely to become the "wind king" of the eastern Pacific this year.
In fact, Hurricane Lee in the North Atlantic is also developing and strengthening, and there is still enough room for development in front of it, and there is very sufficient sea heat near the West Indies, which may also develop into a very powerful hurricane.
Second, or hit North America hard
Many supercomputer models have pointed out that the next huge North Atlantic will be the stage for Hurricane Lee - since this summer, the North Atlantic SST has been severely high, and Lee will quickly develop into a Category 4 or Category 5 hurricane, and it is not ruled out that it may also become the North Atlantic wind king this year. But compared to Hurricane Jova, Hurricane Lee may be one of the most important hurricanes in North America so far this year.
The reason for this is that Hurricane Lee, after passing north of the West Indies, will gradually turn northward and begin to turn around and approach the northeastern United States and eastern Canada. Some previous predictions have pointed out that after the northward Hurricane Lee may turn into a powerful extratropical cyclone hitting the northeastern United States and southeastern Canada, and may even directly hit a number of large cities in the northeastern United States, including New York, if realized, it will bring a fatal blow to the local area.
Third, Japan's sewage exacerbates climate variability
There is no doubt that the United States is surrounded by two rare super hurricanes, Hurricane Jowa and Hurricane Lee. The intensity and path of both hurricanes have attracted the attention of scientists and the public, with some even wondering if it is related to the discharge of nuclear wastewater in Japan. Will Japan's nuclear wastewater exacerbate climate variability, leading to more extreme weather events?
Japanese nuclear wastewater refers to the large amount of radioactive contaminated water produced after the Fukushima Daiichi nuclear power plant leaked in 2011. Due to lack of storage space, the Japanese government began discharging this nuclear wastewater into the Pacific Ocean in August 2023. This decision has sparked strong opposition from the international community, arguing that it will cause serious harm to marine ecology and human health. But the Japanese government insists that after the treatment of the nuclear wastewater, all radioactive materials except tritritium have been removed or lowered below safety standards and will not affect the environment.
However, some meteorologists say that Japan's nuclear wastewater may have a potential impact on the global climate, especially in North America. He explained that when Japanese nuclear wastewater is discharged into the Pacific Ocean, it changes the temperature, salinity and density of seawater, which affects ocean circulation and atmospheric circulation. Ocean circulation refers to the movement of seawater across the globe, which regulates the Earth's temperature and climate. Atmospheric circulation refers to the movement of air in the atmosphere, which can form weather phenomena such as wind, clouds, and rain.
The oceans are Earth's largest heat source and carbon sink, and they play an important role in regulating climate change. If the temperature, salinity, density, etc. in the ocean change, it will affect the stability and strength of the ocean circulation, which in turn will affect the atmospheric circulation and weather system. However, the impact of such emissions on specific weather is still controversial, and some analysts have pointed out that although the total amount of nuclear wastewater discharged by Japan is large, the impact on the global climate is still insignificant. However, many scholars believe that the discharge of nuclear wastewater in Japan is still a very irresponsible behavior, which will not only pose a threat to marine life and human health, but also cannot exclude unpredictable impacts on the global climate.
