In this anniversary issue of Atmósfera we include an excellent revision of the literature on chlorine in the stratosphere prepared by Thomas von Clarmann, who is a senior researcher and head of the Satellite-Borne Remote Sensing of Trace Gases group…

Anomalies of mean monthly air temperature at 50 surface stations in the contiguous United States during the winter months of January, February and March from 1951 to 1980 are statistically screened as functions of earlier, centered or future time means…

Components of the thermotopographic wind regime in the Mexico City basin are examined in their interaction with the heat island induced centripetal circulation. The resulting wind regime is such that convergent surface flow over the city is predominant mainly during…

Smith's (1969) analytical absorption spectrum of the atmosphere is incorporated in a thermodynamic model. This radiative formulation is applied to the infrared region. It computes separately the absorptivity by carbon dioxide and by water vapor, with a high wave length…

Two numerical experiments were performed with a simple energy balance climate model. One is for a global ocean planet and the other one is for a wet land planet. It was found that the tropical rainbelt maximum migrates, for a…

The 12-month Standardized Precipitation Index (SPI) is used to identify and assess drought severity in México during the 1949-2098 period under the A2 emissions scenario of the Intergovernmental Panel on Climate Change (IPCC). The analysis indicates more frequent and severe…

The ejecta ofvolcanism, including gas-to-particle conversions, form atmospheric aerosol layers which influence the radiation processes and in consequence the climate. Thereby, the major explosive eruptions are of predominant interest. They cause stratospheric warmings whereas the atmospheric boundary layer near surface…

This paper studies the influence of the North Atlantic Oscillation (NAO) on monthly, seasonal and annual precipitation regimes in continental Spain. The data used for this study include the monthly rain series of 325 meteorological stations distributed homogeneously over the…

A forecasting model for the mean monthly maximum temperatures (TMaxMean) using an artificial neuronal network (ANN) of the multilayer perceptron type (Multilayer Perceptron, MLP) has been developed. This model forecast the TMaxMean variable one month ahead after the last data…

This paper presents spectral distribution of aerosol optical depth (and derived size distribution), water vapor and ozone in total atmospheric column; in conjunction with particulate mass concentration in the size range from 0.3 to 20 µm and black carbon mass…
