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 main objective of this study is to obtain the spatial distribution of net radiation (RN) in two contrasting vegetation covers (forest and pasture) through the SEBAL algorithm, and to analyze its performance when applied to tropical humid atmospheric conditions.…

Global climate change causes a decrease of precipitation in Turkey, as in many other parts of the world. As a result, droughts have now occurred over a larger area and in a more drastic way than in the past. Determining…

The authors present the evaluative testing of a portable prototype of digital electronic barometer (UBII001). The prototype was developed in Venezuela although it includes low-cost multinational parts. The six year evaluation included response stability against atmospheric pressure variations. The UBII001…

The demographic characteristics of the publications produced by researchers at the Centre for Historical Studies (CEH) of El Colegio de Mexico (COLMEX) from l948 to June 2010 are analyzed. The visibility and impact of the journals used by researchers at…

Human bioclimatic scenarios are presented for Mexican cities with more than a million inhabitants. For this, both urban and global warming were considered, the former having been inferred from demographic data, and the latter from the output of general circulation…

For preparing medium range weather forecasts, two global coarse resolution models at different resolutions were used at the National Centre for Medium Range Weather Forecasting (NCMRWF), India. In order to improve the forecasting skill, an ensemble prediction system (EPS) was…

The current study proposes two methodological approaches for analyzing the effects of climate change on biodiversity, one at the level of bioclimatic zone, and the other one at the species level. Three general circulation models were applied to nine bioclimatic…

We present the results of a study of the dimming-brightening phenomena in the Wider Caribbean. The dataset consisted of time series of global radiation from 30 surface stations covering the period 1961-1990. The stations were distributed over the entire region:…
