Typhoons move more slowly worldwide

According to scientists, over the past 60 years, more rain has fallen on Earth, while storms have moved more slowly.

According to Business Insider, the scientists found that the rainfall is getting more and more abundant than before. These figures from the US National Weather Agency demonstrate this.

In Seattle, in recent years it has been 30-40% more rainy than it was decades ago.

From 1958 until now, storms across the United States have increased from 10 to 70% of water depending on where, the highest is the northeastern sea. In just the last 30 days, the average rainfall on the East Coast from Miami to Washington DC is also about 254mm.

Humidity in the air in this country also increased by 7% compared to before.

Andreas Prein, a scientist from the United States Association of Atmospheric Research Universities (UCAR), said the peak of rainfall in big storms increased by 30% within 60 years.

" Terrifying storms also occur more often. At peak times, rainfall can increase by 101mm / hour," Andreas Prein said.

What is the cause?Human activities increase the Earth's average temperature. Increased temperatures mean an increase in evapotranspiration, thereby increasing rainfall.

"Rising rainfall reflects a serious climate change situation," Angeline Pendergrass from UCAR said.

However, scientists say not every place has increased rainfall. While an area is getting wetter, another area becomes extremely dry.

And once it rains in the arid region, intense floods are more likely to occur because the soil loses its ability to absorb water.

The storms slowed down

According to National Geographic, scientists after analyzing more than 22 recent storms have concluded that global storms tend to move more slowly.

Dr. James Kossin from the US National Oceanic and Atmospheric Administration (NOAA) said that from 1949 to 2016, global storms slowed by about 10%.

In some special regions, such as the North Pacific, the speed of storms is 1/3 lower than before.

For example, Hurricane Ike killed 100 people and destroyed most of the United States in 2008, moving about 17% slower than the average, but the wind increased by 13%.

"Nothing is good, the intensity of the storm remains the same, meaning that the time to endure with the storm increases, the damage will be more," said James Kossin.

Kossin has also been studying storms for more than 70 years, but he cannot find out why the storms are getting slower.

Christina Patricola, an ecologist and environmentalist at Lawrence Berkeley National Laboratory in the US, said: "The fact that slower storms don't surprise me. What I'm surprised here is that the pace of reduction is too strong. " .

In addition, another question is whether the time when the storm is in a state of "standing still" in a certain position will continue to increase? "However, it's not all good," said Christina Patricola.
