It is that the hurricane is fed by the heat of the waters that circulate over it. The hotter this water is, the more energy you gain. That’s why for as long as we’ve been talking about global warming, we’ve speculated that warming could lead to either an increase in the number of hurricanes or an increase in the number of more powerful hurricanes.
So far, we still don’t have an answer, just as we don’t know if there is a threshold, in degrees Celsius, beyond which coastal populations will suffer the consequences. But records like the one on April 1, or an increase in the number of times a year the average exceeds 20 degrees, with the greatest interest By meteorologists, climatologists and oceanographers.
Especially since it’s not just a one-day record we’re talking about this time around. For 5 days, from April 1 to April 5, the average temperature (excluding the polar regions), within a few hundredths of a degree, was maintained at about 21.1 degrees, according to Satellite data collection by the US Oceanic and Atmospheric Agency (NOAA) and the University of Maine. It stayed about 21.0 degrees from April 6 to 26, which is about a tenth of a degree warmer than the average for all previous years since 1981, for which this satellite data was compiled. The current track shows that [la température] exceeds standards, crushing previous records,” comment In the British newspaper Watchman Climate scientist Matthew England.
The planet may be heading for an El Nino this fall – a natural phenomenon that traditionally adds to widespread warming. So these numbers will be a bad omen Nothing can explain Why is the temperature so high, so early in the year.
What is certain is that the oceans have accumulated more heat in the last 15 years compared to the past five decades, but that’s a long-term trend, which also doesn’t explain these April 2023 numbers.
