As a result of global climate change, the frequency and intensity heat waves have increased significantly. According to World Meteorological Organization (WMO), extreme temperatures in southwestern Pakistan exceeded 54 °C successive years. The identification assessment heat-health vulnerability (HHV) are important for controlling heat-related diseases mortality. At present, many definitions. To...

Összefoglaló. A WMO 2021 elején kiadott állapotértékelője szerint a COVID–19 miatti korlátozások ellenére az üvegházhatású gázok légköri koncentrációja tovább emelkedett. tengerszint emelkedés közelmúltban gyorsult, rekordmagas volt jégvesztés Grönlandon, Antarktisz olvadása is gyorsulni látszik. Szélsőséges időjárás pusztított, élelmiszer-ellátási gondok léptek fel, és 2020-ban hatásával együt...

Papers summarizing "Human and Economic Impacts of Weather Events" published each year in the WMO Bulletin by S. G. Cornford [1] have shown growing importance of weatherrelated disasters within world community. Such papers are a good summary of the events, especially with respect to human and property losses related to different seasons and continents Since 1994 year when “Guidelines for Natural...

This paper addresses the methodological concerns in quantifying urban heat island (UHI) intensity in Hong Kong SAR, China. Although the urban heat island in Hong Kong has been widely investigated, there is no consensus on the most appropriate fixed point meteorological sites to be used to calculate heat island intensity. This study utilized the Local Climate Zones landscape classification syste...

Weather information provides a safe working environment by contributing to the economic activity of the nation, and plays role of the prevention of natural disasters, which can cause large scaled casualties and damage of property. Especially during times of war, weather information plays a more important role than strategy, tactics and information about trends of the enemy. Also, it plays an es...

1729 NOVEMBER 2007 AMERICAN METEOROLOGICAL SOCIETY | E very year, weather affects society in innumerable ways. Extreme weather—such as hurricanes, tornadoes, and floods—garners the most attention because of the damage extent, extreme conditions, economic loss, injuries, and deaths often associated with these events. But, nonextreme weather, including nonsevere thunderstorms, aboveor below-avera...

The prediction of weather generally means the solution of differential equations on the base of the measured initial conditions where the data of close and distant neighboring points are used for the calculations. It requires the maintenance of expensive weather stations and supercomputers. However, if weather stations are not only capable of measuring but can also communicate with each other, ...

An operational hydrological ensemble forecasting system based on a meteorological ensemble prediction system (M-EPS) coupled with a hydrological model searches to capture the uncertainties associated with the meteorological prediction to better predict river flows. However, the structure of the hydrological model is also an important source of uncertainty that has to be taken into account. This...
