This study investigates the characteristic differences of tropical disturbances that eventually develop into tropical cyclones (TCs) versus those that did not, using global daily analysis fields of the Navy Operational Global Atmospheric Prediction System (NOGAPS) from the years 2003 to 2008. Time filtering is applied to the data to extract tropical waves with different frequencies. Waves with ...

Within the present study we shed light on the question whether objective circulation patterns (CP) classified from either the 500 HPa or the 700 HPa level may serve as predictors to explain the spatio-temporal variability of monsoon rainfall in the Anas catchment in North West India. To this end we employ a fuzzy ruled based classification approach in combination with a novel objective function...

Atrial natriuretic peptide (ANP) is produced and released by mammalian cardiomyocytes and induces natriuresis, diuresis, and lowering of blood pressure. The present study examined localization of ANP and a possible role of the hypothalamic-pituitary-adrenal axis (HPA) activity on the expression of proANP gene in the heart. The Sprague Dawley (SD) and Lewis (LE) rat strains were used. The animal...

Oxidized mercury (Hg(II)) is chemically produced in the atmosphere by oxidation of elemental mercury and is directly emitted by anthropogenic activities. We use the GEOS-Chem global chemical transport model with gaseous oxidation driven by Br atoms, to quantify how surface deposition of Hg(II) is influenced by Hg(II) production at different atmospheric heights. We tag Hg(II) 10 chemically produ...

[1] We characterize the horizontal and vertical distribution of tropospheric ozone measured by the Tropospheric Emission Spectrometer (TES) over North Africa, the Middle East, and Asia. Studies have shown that the summertime circulation associated with the Asian monsoon significantly influences the spatial distribution of ozone and its precursors. However, there have been limited observations o...

OBJECTIVE Although left dorsolateral prefrontal cortical (DLPFC) repetitive Transcranial Magnetic Stimulation (rTMS) is used to treat major depression, its underlying neurophysiological working mechanism remains to be determined. Prior research suggested that the clinical effects could be mediated by affecting the hypothalamic-pituitary-adrenal (HPA) system, but experimental studies in healthy ...

The Brewer–Dobson circulation (mainly meridional circulation) is very important for stratospheric ozone dynamics and thus for the overall state of the stratosphere. There are some indications that the meridional circulation in the stratosphere could be longitudinally dependent, which would have an impact on the ozone distribution. Therefore, we analyse here the meridional component of the strat...

Abstract Based on daily meteorological observation data in South China (SC) from 1967 to 2018, the spatiotemporal characteristics of precipitation SC over past 52 years were studied. Only 8% stations showed a significant increase annual rainfall, and there was no negative trend at any weather confidence level 90%. Monthly rainfall most decreasing increasing trends April November, respectively. ...

ackground: Knowing the human platelet antigens (HPA) and genes frequency in different populations is important not only for population studies but also for clinical transfusion practice. HPA genes frequency in Iran is not evaluated, so we investigated the HPA-2, HPA-3, and HPA-5 frequency and their polymorphism. Materials and Methods: DNA from 120 Iranians (99 Iranian blood donors and 21 patie...

Abstract Four meteorological components (geopotential height Z , air temperature T dew point Td, and relative humidity RH) collected from ERA-5 ERA-Interim were compared with the observations of nine radiosonde stations different climatic changes, at isobaric levels (850, 700, 500, 200 hPa) during period 2000–2017, in order to assess accuracy aforementioned reanalysis datasets. The results show...
