Study: Climate change makes storms more deadly Environment and climate

A new study showed that the most powerful oriental northern storms (Normis), which are destructive and often fatal storms hitting the eastern coast of the United States with rain, snow, and overwhelming floods, are increasing and destroyed due to the effects of climate change.

The study, published in the journal of the National Academy of Sciences, indicated that the most powerful northeastern storms, albeit less frequent, are increasingly intense, accompanied by strong winds and heavy rains.

This is a worrying trend of storms that caused damage to tens of billions of dollars, in addition to injuries and deaths.

Scientists used historical and algorithms to track hurricanes to analyze the “Normis” storms between 1940 and 2025, and together they gathered a digital atlas for these storms, and they analyzed 900 storms in general.

The analyzes found that the maximum wind speed in the most severe storms of “Normis” increased by 6% since 1940, and rainfall and snow caused by these storms also increased by about 10%.

The normster storms are usually between September and April, and its energy is derived from contrast in temperatures between the cold polar air coming from the north and the warm wet air coming from the Atlantic Ocean.

They are strong and destructive hurricanes often, mainly affecting the eastern coast of North America. Some of these weather phenomena were so severe that they deserved the names of the “ideal storm”, “storm of the century” and “snowstorm”, and some of them became known as borrowed names that appear as addresses of disasters.

Historical records and climate models indicate that these destructive storms have become less common due to the high temperature of the climate. However, its lack of frequency does not necessarily mean its low intensity.

The researchers believe that these increases in density may have been caused by the common effect of the high temperatures of the ocean and an increase in the exhaustion of moisture in the warm atmosphere. These storms constitute a major threat to the densely populated cities along the eastern coast of the United States and other regions.

Less and more destructive

Scientists are unanimously unanimously overwhelmed by “Normis” storms in a more precautionary world, because the Arctic is heated at a faster rate than the rest of the northern hemisphere, which means that the contrast in temperatures, which nourishes these storms, will be less.

However, what was not clear is what will happen because of the severity of these storms, which often does not have sufficient studies.

Studies have indicated slight or non -existent changes in the intensity of the northeastern winds, but they often failed to evaluate the main factors directly, such as wind speed and rainfall trends.

In general, strong storms are formed when evaporation increases with high temperatures, as well as heat transfer from oceans to air.

As storms have passed through the warm oceans, they attract more water and heat vapor, which increases the energy of the storm, with heavy rains, stronger winds and greater floods when the storms hit the Earth.

The tide storm also occurs when the water rises above its normal levels and the wind pushes it inside.

This phenomenon is exacerbated due to sea level rise, which occurs due to global global warming caused by human activities with ground ice melting and the expansion of warm ocean water.
