Sugarcane cultivation is an agricultural activity of worldwide importance.This crop has been cultivated in Mexico for centuries, impacting important productive areas like the study region called Huasteca Potosina which located at Central-East part Mexico.The relationship between soil conditions, weather and production per hectare allows identifying edaphological climatic conditions (aptitude levels) cultivating sugarcane area.The objective this research work to analyze relation hectares...

Numerical simulations revealed a profound interaction between the severe dust storm of 2007 caused by Santa Ana winds and Gulf California. The weather research forecasting model coupled with chemistry module (WRF-CHEM) hybrid single-particle Lagrangian integrated trajectory (HYSPLIT) allowed for estimation meteorological dynamic aspects event deposition on surface waters California erosion entrainment particles from surrounding desert regions. emission rates three chosen areas (Altar desert,...

Mexico is vulnerable to extreme climatic events; however, their impact not uniform in all the country. This study presents an analysis of temperatures 12 Mexican cities, modeled under assumption a non-stationary climate. Temporal trends were estimated from available climatological base maximum and minimum with non-parametric tests Mann-Kendall Sen’s slope method, generalized value (GEV) distribution was used model both temperatures. A likelihood ratio test Akaike Bayesian information...

Transport is one of the sectors with highest greenhouse gas emissions (GHG) that imperative to reduce in order decrease global warming. Although modern vehicles and arterial roads have adopted technological structural improvements enhance fuel use efficiency, emission gases into atmosphere by transport sector has been increasing different Mexican cities. In generating mitigation strategies, modeling scenarios decreased equivalent carbon dioxide, CO2e emissions, may be useful as an evaluation...

In this paper, four probability functions are compared with the purpose of establishing a methodology to improve accuracy estimated wind energy in desert city northwestern Mexico. For statistical modeling, 3 time series speed data were used, corresponding years 2017, 2018, and 2019, recorded sonic anemometer at sampling frequency 10 Hz. From these, analysis is performed different stationarity periods (5, 30, 60, 600 seconds). The estimation parameters characterizing density was using...

In this paper, four probability functions are compared with the purpose of establishing a methodology to improve accuracy wind energy estimations in desert city Northwestern Mexico. Three time series speed data corresponding 2017, 2018, and 2019 were used for statistical modeling. These recorded sonic anemometer at sampling frequency 10 Hz. Analyses based on these performed different stationarity periods (5, 30, 60, 600 s). The estimation parameters characterizing density (PDFs) was carried...

Northwestern Mexico has a desert climate with high solar resources. Clear skies and low humidity during most of the year favor their use. In winter, arrival cold air masses from polar latitudes cause instability abrupt changes in atmospheric variables, increasing error short-term forecasts. This work focuses on evaluation Weather Research Forecasting (WRF) model for predicting global horizontal irradiance (GHI), considering different parameterizations shortwave longwave radiation influence...

Abstract The objective was to analyze how representative tropospheric NO 2 column densities are of surface measurements under different atmospheric stability conditions in the air basin two border cities: Calexico, United States, and Mexicali, Mexico. columns were measured by Ozone Monitoring Instrument (OMI) on NASA Aura satellite. concentrations meteorological parameters also for comparison. Specifically, correlations between OMI according Pasquill‐Gifford (P‐G) Monin‐Obukhov (M‐O)...

Roof surfaces on which air conditioning equipment is installed cause significant temperature increases around the condensers due to roof thermal properties, resulting in excess electrical energy consumption and greenhouse gas (GHG) emissions. An experiment quantify such excesses during summer was conducted at a university campus Mexicali, Mexico. The temperatures surface for three types of roofs were recorded. Temperatures (condenser inlet temperatures) used as input data priori estimate...

This study focuses on the impact of local atmospheric conditions photovoltaic panels and their effect power generation. The aimed to develop multiple linear regression models that relate meteorological variables, dust, panel's output parameters with its generated power. An experiment was conducted using two identical installed in Mexicali, Baja California, Mexico; one panel kept clean other dirty, both were exposed arid characterizing region. These systems integrated a weather station,...
