Glaciers in México have been present for the last decades on highest mountains of México: Iztaccíhuatl,Popocatépetl and Citlaltépetl.In 1964 size twelve glaciers was measured at Iztaccíhuatl volcano using aerial photographs resulting an extension 1.4 km2. At time this review, El Pecho is only remaining glacier mountain which exceeds projections proposed earlier. Although much glacial retreat related to climate change, situ...

Tropical cyclones (TCs) are natural systems that develop over ocean basins and key components of the atmospheric activity during warm season. However, there still knowledge gaps about combined positive negative TC impacts on structure function coastal socio-ecosystems. Using remote sensing tools, we analyzed frequency, trajectory, intensity 1894 TCs from 1851–2019 to identify vulnerable “hotspots” across Yucatan Peninsula (YP), Mexico. A total 151 events hit YP, with 96% landings eastern...

Abstract Thunderstorm and hailstorm environments from 1981 to 2018 are analysed using the proximity soundings approach based on European Centre for Medium‐Range Weather Forecasts Reanalysis v5 (ERA5) reanalysis dataset. Given nature of severe weather dataset, four 0000, 0600, 1200, 1800 local time were retrieved per day with hail activity or thunderstorms. After quality control, a total 30,760 vertical profiles used grouped seasonally spatially consider variation convective environments....

In this study, a detailed analysis of the measurements made on Glaciar Norte Citlaltépetl volcano in 1958 by Lorenzo (1964) is conducted. A series inconsistencies are evident when comparing dimensions volcano's glaciers and those Popocatépetl Iztaccíhuatl volcanoes. From these it was concluded that delimitation Citlaltépetl's wrong values exaggerated true conditions ice bodies for 1958. paper we explain methodology applied reconstruction reconstruction, new more realistic value glaciated...

This study shows the dramatic but probable future evolution of Mexico's largest glacier. Mass and energy balances this glacier have been previously studied, as well reconstructions its up to present time. In work, for first time, real is compared with years models evolution. Two dynamic thickness developed based on a network stakes ground penetrating radar complemented by geometrical characterizations bed shape. Calculated mean annual mass balance leads equilibrium line altitude be...

Thunderstorms are known to have the potential cause damage population. In Mexico, these weather events can bring threats such as lightning, hail, damaging winds, and even tornadoes. Various parameters indices been developed for mid‐latitude regions improve forecasting reduce from thunderstorms; however, they do not consider specific conditions of tropical subtropical environments. This research used a comprehensive set thunderstorm reports proximity‐sounding approach using ERA5 reanalysis...

The glaciers of Mexico are very small ice bodies located on top the highest mountains Mexico. They represent a natural gauge for climatic changes at 19ºN latitude where no other around world. Glaciar Norte glacier Citlaltépetl Volcano, Mexico, has been retreating in huge scale, just like close to tropics. Following current trend world, this will probably disappear before mid-century and with its disappearance an important be gone. Therefore, it is identify factors influencing retreat...

The evolution of Mexican glaciers (19° N) in the climate context is poorly understood despite these are important indicators regional change. detailed patterns glacier recession since Little Ice Age (LIA) have exacerbated during past years and decades. Their relationship to local change needs further analysis. This study compares changes largest Mexico, Glaciar Norte (GN), on Citlaltépetl Volcano with temperature, precipitation, surface energy balance variations that were considered as part...

Abstract Northwest Mexico (NWM) is an extensive region with a humid and unstable environment leading to atmospheric convection during the North American monsoon. Occasionally, extreme events are associated severe weather, including deep convection, heavy rainfall frequent lightning. Based on period from July through September 2009–2018, present study investigates general characteristics of convection. Geostationary satellites were used document three‐dimensional cloud cover structures over...

Abstract. Satellite imagery and net radiation data collected between 2001 2007 for Citlaltépetl Volcano confirm the dramatic shrinkage of Glaciar Norte elimination Jamapa Chichimeco glacier tongues. The rapidly retreated 2002 while this retreat decreases considerably. tongues disappeared by as compared to geometry shown 1958. lost about 72% its surface area 1958 2007. Recently, ice loss appears be accelerating evidenced 33% areal in just 6 yr At rate glaciers would gone from volcano year...

Abstract Freezing temperatures are responsible for population and ecosystem damage, their spatial extent, frequency, duration may change in a warming world. Few studies available concerning the analysis of extreme freezing Mexico, none have evaluated probability occurrence. This study identified characteristics past recent events by applying statistical crossing theory method to calculate cumulative density function (CDF) minimum temperature ( T min ) values throughout Sonoran Desert,...

Glaciers have played a very important role in controlling the climate during most of geologic history our planet Earth. Of course, glaciers always been at higher latitudes (north and south), some on high-altitude mountains. Current Mexico are those inherited from Last Glacial Maximum, (26000 - 19000 years before present), increasing size period Little Ice Age (1300 to 1850 common era), they unique several ways; located 19° north latitude, received snow precipitation both Pacific Ocean Gulf...
