Such a phenomenon had not been seen for four decades. In the last days, the Cyclone Yaku generated heavy rain in Tumbes, Piura and Lambayeque, a panorama that can extend to La Libertad, Áncash and Lima, depending on the National Service of Meteorology and Hydrology (Senami).
The agency said that Yours It is associated with warming sea surface temperature and the second band of the Intertropical Convergence Zone (ITCZ). Its presence in the Pacific is unusual and experts have defined it as an “unorganized tropical cyclone”.
for the meteorologist Abraham Levy, Known as the “weather man”, the Cyclone Yaku It would not reach the coasts of the country, despite the fact that its impacts are felt with the danger of floods and mudslides, and the storms that have flooded streets and populated centers.
Yaku presents conditions similar to the El Niño phenomenon of 1997 and 1982. “A cyclone must have a temperature above 26°C and the wind, a closed circulation in favor of the clockwise direction. There was no similar condition (in this case), not exactly like a cyclone, but similar,” he said. RPA Benito Valderrama, Senamhi Specialist in aeronautical meteorology.
Valderrama has ratified that it is virtually impossible for Yaku to become a hurricane since projections of the direction of the cyclone’s core indicate that, if the intensity of the temperatures where it is located is lost, it will begin to dissipate.
Additionally, it is expected to head southwest where the Peruvian sea does not exceed the required minimum of 26.5°C, so when it gets there the dreaded cyclone will disappear.
The bone hurricanes, cyclones and typhoons it is the same meteorological phenomenon: a storm system. However, scientists call these storms differently depending on where they occur, examine National Geographic.
When one of these storms occurs in the North Atlantic, the Caribbean and the northeast Pacific, it is called a hurricane. When found in the Pacific Northwest, they are called typhoons.
“We have a cyclone that It’s a whirlwind, not a hurricane which was configured in front of the north of Peru and which circulates the air from north to south (…) first it invaded Tumbes, now Piura then in a few days the coast of Lambayeque and La Libertad and brings the classic El Niño effects”; Nuanced Lévy.
The specialist indicated that the Cyclone Yaku The arrival of autumn would change, because by the time the sun reaches the equinox, and heads north, the atmosphere will begin to cool, and precipitation conditions with warm seas can generate an extension of the rainy season to the north.
“If this warming extends a little beyond April and takes time to recede, conditions could deteriorate and the genesis of El Niño it could be closer than predicted in climate models in the second half of this year,” Levy said.
