Nevadas en la CDMX

Title
Nevadas en la CDMX
Abstract

Las nevadas son precipitaciones que consisten en la caída de agua en estado sólido en forma de pequeños cristales de hielo que caen individualmente o agrupándose en copos de nieve, principalmente en las partes altas de las montañas y que en ocasiones llegan a los valles altos.10 Las bajas temperaturas que se presentan durante los meses de noviembre a marzo –teniendo en diciembre y enero el mayor impacto– han ocasionado caída de nieve o aguanieve o nevadas ligeras en las zonas altas del sur...
