Contributions are welcomed on original research leading to the characterization and understanding of air-sea interactions as they relate to meteorological phenomena and their influence on climate. Contributions are also accepted on the interactions between the atmosphere and the biosphere as they relate to air quality and climate. Se analizan las posibles consecuencias de lo anterior en la ciudad de Mexicali.. Extreme weather events can have severe consequences for the population and the environment. Therefore, in this study a temporal trend of annual temperatures was built with a time series from to for Mexicali, Mexico, and estimates of 5- to year return periods are provided by modeling of summer maximum and winter minimum temperatures. The generalized extreme value GEV distribution was applied to the approximation of block maxima and the generalized Pareto distribution GPD to values over a predetermined threshold. Due to the non-stationary characteristic of the series of temperature values, the temporal trend was included as a covariable in the location parameter and substantial improvements were observed, particularly with the extreme minimum temperature, compared to that obtained with the GEV with no covariable and with the GPD. A positive and significant statistically trend in both summer maximum temperature and winter minimum temperature was found. The foreseeable consequences on Mexicali city are discussed.. Various studies have indicated that changes in the frequency and intensity of extreme climate events, such as heat waves, droughts, and foods, can be expected in several parts of the world due to global climate change IPCC, Changes in these extreme events are particularly important for society and the environment because, by definition, they occur outside the usual range of adaptability; therefore, they can have severe impacts and significant negative economic effects Kharin et al. Variations in temperature extremes are of particular importance due to their relationship to biodiversity and human thermal comfort, as well as their use in climate variability and climate change impact assessments in sectors such as agriculture and energy demand. In the period from to , the increase in average terrestrial temperature was estimated at 0. According to some projections, extreme heat and cold events may increase during this century, resulting in increased mortality Curriero et al.

Therefore, the GPD was adjusted to the maximum daily temperatures of Mexicali data points for the period Mar

Se encuentra localizada en el extremo noroeste del valle de Mexicali , en la frontera con los Estados Unidos. Eso obliga a que haya asentamientos de los trabajadores. La superficie sembrada con este cultivo se fue ampliando en la medida que se incrementaba la red de canales de riego. El Valle de Mexicali fue afectado de manera grave, al perder comunidades casi enteras sus viviendas y tierras de cultivo, por las inundaciones causadas por el terremoto. Venustiano Carranza y de Norte-Sur de la Av. No obstante numerosos proyectos e inversiones anunciados, casi nada se ha realizado hasta hoy. Hasta ahora se ha realizado un solo pago. Mexicali cuenta con una comunidad empresarial, con gran experiencia en negocios internacionales y dispuestos a co-invertir. En el Valle de Mexicali es donde se practica la agricultura de riego, con una superficie bruta de ha.

This study is important given the vulnerability to extreme temperature events shown on multiple occasions in Mexicali. Science and Technology Branch, Environment Canada, 24 pp. Ruoho-Airola, T. Sites that had native or agricultural soil until a few years ago are now concrete slabs. We will review the data in question. A positive and significant statistically trend in both summer maximum temperature and winter minimum temperature was found. In the present study, mean excess function methods were used as a starting point, and the stability assessment of parameter estimators was used for selecting the threshold value, based on adjusting the GPD by postulating a range of different u thresholds. Zhang, G. Current Station. See more Top Video Stories. This study considered the following: a annual maximum and minimum temperature extremes, b daily maximum and minimum values of temperature for the selected period. Therefore, in this study a temporal trend of annual temperatures was built with a time series from to for Mexicali, Mexico, and estimates of 5- to year return periods are provided by modeling of summer maximum and winter minimum temperatures. Results of the trend analysis are summarized in Table I , and can be seen in Figure 2. The time of Actual Sunset minus the time of Actual Sunrise.

The air quality is generally acceptable for most individuals. However, sensitive groups may experience minor to moderate symptoms from long-term exposure.

Extreme weather events can have severe consequences for the population and the environment. Valdez-Cepeda, B. Labajo, M. We will review the data in question. Please select the information that is incorrect. The evidence of changes depends on the region considered, the method of analysis, and the available data period. Trends in rain fall and extreme temperatures in northwestern Mexico. Brito-Castillo, S. High 69F. For the GEV given in 1 , z p is obtained from the following:. The first consideration leads to the application of the block maxima statistical approach and the second to a threshold value approach. The foreseeable consequences on Mexicali city are discussed. To summarize, of the 16 records checked only 10 suspected as erroneous were identified, meaning 0. Current Station. Only those values that were confirmed to be erroneous were set to missing and deleted from further analysis.
