Experts oceanic and atmospheric administration and Pacific Northwest national laboratory recorded an abnormal increase in the strength of Atlantic hurricanes. According to the findings of researchers, the main cause was a natural climate cycle called the North Atlantic oscillation. Probably, global warming also contributes, making the strength of storms is unpredictable. About it reported in a press release on EurekAlert!.

With the rapid increase in the intensity of the cyclone, its speed is increased by 36 kilometers per hour for 24 hours. In 2017, it has been observed in such storms as “Harvey”, “Irma”, “Jose” and “Maria”.

The researchers analyzed satellite data on the strength of storms over the past 30 years and found that the average increase in wind speed from hurricanes currently 21 kilometers per hour more than in the past. Every decade this feature was up seven kilometers per hour.

The wind speed is influenced by various factors, including the temperature at the sea surface, humidity, direction and speed of growth, as well as the heat content in the surface layer of the ocean. The North Atlantic oscillation, first discovered in 2001, mainly affects the sea surface temperature, making it unstable for decades. Now this phenomenon is observed in the Central and Eastern Atlantic. Scientists admit that it may experience the effects of global warming.

Tropical storm “Harvey” has caused catastrophic flooding in Texas in 2017 and became the strongest after hurricane Katrina in 2005. The result of the disaster killed 83 people and total damage was estimated at $ 70 billion.
