The relationship between total column ozone (TCO) and the development of a cyclonic system that occurred in the period from January 18 to January 25, 1981 has been studied using the ERA-Interim reanalysis database. It was found that TCO increases and dec...

This study attempts to understand why the frequency of tropical cyclones (TC) over the western North Pacific (WNP) was a record low during the 2010 season, by analyzing the effect of several large-scale factors. The genesis potential index (GPI) can repr...

Based on a regional drought index carried out by other authors (Minetti et al., 2004), it has been possible to associate droughts with atmospheric pressure anomalies in South America. We attempted to group the fields of atmospheric pressure anomali...

The principal area of tropical cyclogenesis in the tropical eastern Pacific Ocean is offshore in the Gulf of Tehuantepec, between 8 and 15º N, and most of these cyclones move towards the west and northwest during their initial phase. Historical analys...

Cyclones and anticyclones are the dominant synoptic scale meteorological systems in midlatitudes. An attractive way to study dynamical aspects of these structures is provided by the use of potential vorticity (PV) framework. In ...
