Resumen

Las invasiones de aire polar en el Golfo de México han aumentado su frecuencia e intensidad debido a cambios en la circulación general ocurridos a partir de la década de los años sesenta. El resultado ha sido un decrecimiento de la temperatura y un incremento de las lluvias invernales. La principal estación de lluvias, centrada en el semestre de verano, está relacionada con la llegada, al área, de la corriente tropical de los alisios húmedos con su constelación de perturbaciones.

 

Abstract

A description is made of the principal weather systems that affect the region of the Gulf of Mexico and its adjacent Mexican coastal areas. During the semester centered in winter cold polar outbreaks visit the area producing a secondary rainy season in this period. As a result of change in the general circulation during the 60's the frequency and intensity of 'Northers' has appreciably increased; as a result winter rainfall has augmented and corresponding temperatures have fallen in the area during the last decade. The main rainy season is centered in the summer when hurricanes and other tropical disturbances are the main rainproducing systems.
