one of the effects of climate change is the possible increase in both frequency and intensity of extreme weather events. extreme weather and climate events have a major impact on ecosystems and human society due to their severity and the fact that they often occur unexpectedly. in warmer climates and during transition seasons, cold extremes have agricultural impacts that are manifested in the d...

in order to have spatial and temporal analysis of iran extreme cold days' trend, the average of daily temperature data from 663 synoptic and climatologic stations of iran during the period of 1961/21/03 to 2004/19/03 were used. then, temperature data on 15*15 kilometer pixels were interpolated using kriging method for iran. the extreme cold days were identified by normalized temperature di...

introduction: extreme altitude travel has gained popularity globally for adventurous, scientific, and military endeavors. cerebral venous sinus thrombosis (cvst) at extreme altitude is a rare, covert, and emergent condition requiring immediate intervention. case presentation: a case of cvst masqueraded as high altitude cerebral edema (hace) at 6700 m/22000 ft in karakoram himalayas. atypical ol...

Introduction: Extreme weather or climate, including heat waves and cold waves, is considered a health issue causing adverse effects on health, such as cardiovascular diseases (CVDs), mortality and morbidity. Thus, this systematic review aimed to study the impacts of extreme ambient temperature on cardiovascular outcomes. Material and Methods: This study was carried out based on the Preferred R...

to doing this research daily interpolated temperature data from asfezari data base have been used. in order to recognition extreme cold days, the normalized temperature deviation index (ntdi) applied. then the index sorted according to extensive and severity and first 500 days selected for analysis. the geopotential height data extracted from www.esrl.noaa.gov data base. the thickness anomaly c...

Forecasted changes in global climate predict not only shifts in average conditions but also changes in the frequency and intensity of climate extremes. In the subtropics, the passage of extreme cold spells functions as a major structuring force for ecological communities, and can incur substantial losses to biodiversity, agriculture, and infrastructure. If these events persist in the future, it...
