This article explains the reasons for long-term variability in sunshine duration (SD) Central Europe. It presents a recently discovered mechanism regulating changes duration, not described so far literature. The periods of global dimming and brightening were linked with annual frequency macrotypes middle-tropospheric circulation surface component thermohaline North Atlantic (NA THC). On basis t...

Solar radiation data are required for many applications and areas of research. In order to achieve this, several empirical models have been suggested predict the global solar in Turkey other countries. The different meteorological as radiation, sunshine duration, temperature, atmospheric pressure, wind speed relative humidity were measured by Eskisehir Osmangazi University during period between...

daily discharge data of 12 hydrometric recording stations in atrak river basin were manipulated to calculate low flows for 7-day duration for studying hydrological drought using regional analysis method. using regression models, the low flows for 7-days duration of 10-year return period were calculated and regional low flows were estimated for 20 stations. daily data in each station used to sim...

tion, and thought that visual solar radiation might provide protection from developing MS. In 1970, a study from Switzerland (which is on a similar latitude in the northern hemisphere as Tasmania is in the southern hemisphere) [5] showed a higher clinical RR in winter and spring months, and a later study (also from the northern hemisphere) [6] of seasonal fluctuations in Gd-enhancing lesions on...

This study was conducted to assess the impact of growing condition variables on alfalfa (<italic>Medicago sativa</italic> L.) productivity. A total 197 yield results were acquired from field trials by South Korean National Agricultural Cooperative Federation or Rural Development Administration between 1983 and 2008. The corresponding climate soil data collected database Meteorologic...

Changes in the components of radiation regime solar during periods intense droughts and their comparison with average values for 1991-2020 Ukraine are given. Drought is a complex dangerous natural phenomenon caused by anticyclonic nature atmospheric circulation, long-term transformation slow-moving air masses over large areas. A dynamic processes leads to its development. They facilitated an in...

To quantitatively reveal the characteristics of spatial and temporal distribution influencing factors maize water requirement in Shaanxi Province, Penman-Monteith model path analysis were used to systematically analyze interannual variation at different growth stages three climatic zones Province. And relationship between meteorological based on daily data Province for past 60 years. The result...

In most of England and Wales the incidence of malignant melanoma of the skin has risen rapidly in recent years, especially in women. Mean incidences in the 14 English health regions and Wales correlated negatively with latitude and positively with hours of sunshine, suggesting that exposure to sunshine was an important causal factor. Male and female incidences within a region tended to show sim...

BACKGROUND Dengue is a leading cause of severe illness and hospitalization in Vietnam. This study sought to elucidate the linkage between climate factors, mosquito indices and dengue incidence. METHODS Monthly data on dengue cases and mosquito larval indices were ascertained between 2004 and 2008 in the Dak Lak province (Vietnam). Temperature, sunshine, rainfall and humidity were also recorde...
