Earlier this week it was intriguing that while in Pachuca the heat peaks reached 27 degrees Celsius, in some nearby places the temperatures were below zero and fell Aguanieve.
From why this contrast spoke to AM Hidalgo Numa Pavón Hernández, research professor at the Institute of Basic Sciences and Engineering (ICBI) of the Autonomous University of the State of Hidalgo (UAEH).
He explained that there are diverse factors that prevented in the capital of Hidalgo Cayera snow.
One of these phenomena is the so -called heat islands, which is common in large cities such as Pachuca, derived from the accelerated urbanization and the gigantic cement spot that increases heat. In addition, it serves as a natural barrier to the cold fronts and moisture of the Sierra Madre Oriental.
The expert, who has the specialty in weather and doctorate in ecology and resource management, explained that in recent days a cold front and a mass of polar air from the Arctic entered the country. “They come with a low altitude, as if they were sweeping, and clashes with the mountain range of the Sierra Madre Oriental.”
That mountainous formation is like a wall that covers the Pachuca region in the so -called volcanic axis. On the other hand, in other locations near Pachuca, but that are more oriented towards the Gulf of Mexico, humidity suddenly rises and precipitates in the form of aquanieve.
That was what happened to provide the show of extraordinary snowfall in municipalities such as Zimapán, Xochicoatlán, Tenango de Doria, Zacualtipán, Tlanchinol, Blanca Agua, Nicolás Flores and Molango. In addition, according to Civil Protection report, that rain and aguanieve phenomenon occurred in Singuilucan, a municipality that is reached by the road from Pachuca in less than 20 minutes.
While snow fell in other locations, in Pachuca there were temperatures from slightly cold to temperate and warm. This differentiation is derived from the heat islands and other phenomena, such as high atmospheric pressure, which allowed skies clear in Pachuca.
Therefore, earlier this week and, mainly, on Tuesday, January 21, Pachuca did not reseather the fall of Aguanieve, said Pavón Hernández.
