Sleep and the hypothalamic-pituitary-adrenocortical (HPA) activity are two biological processes that play a vital role for physical and mental health as well as general well-being. The aim of this cumulative dissertation containing three studies is to complement and extend existing research on the role of sleep and the HPA activity for psychosocial adjustment during childhood and adolescence, a...

Stratospheric and middle-mesospheric ozone profiles above Bern, Switzerland (46.95 N, 7.44 E; 577 m) have been continually measured by the GROMOS (GROundbased Millimeter-wave Ozone Spectrometer) microwave radiometer since 1994. GROMOS is part of the Network for the Detection of Atmospheric Composition Change (NDACC). A new version of the ozone profile retrievals has been developed with the aim ...

There are frequent and intensive periods of heavy rain in the arid areas southern Xinjiang. This study uses a typical rainstorm process South Xinjiang Basin to investigate weather, physical mechanisms, mesoscale characteristics, income expenditure characteristics water vapor sources, analyzing them using observation data from regional automatic stations, ERA5 reanalysis data, multi-source satel...

East Asia has experienced rapid development with increasing carbon monoxide (CO) emission in the past decades. Therefore, uplifting CO from the boundary layer to the free troposphere in East Asia can have great implications on regional air quality around the world. It can also influence global climate due to the longer lifetime of CO at higher altitudes. In this study, three cases of high CO ep...

introduction hazards can be divided into two main groups: one based on origin and other based on speed of occurrence. from view point of speed, the hazards divided into catastrophe and gradual types. for example earthquake, flooding, landslide, avalanche and intense rainfall especially hail are classified into catastrophe events. gradual events include drought, global warming and soil creeping....

This article explores the relationship between vertical wind shear (VWS) and tropical cyclone (TC) genesis in Mozambique Channel (MC) for period 1979–2019. Additionally, SST, low-level relative vorticity, 700 hPa humidity upper-level divergence were also analyzed peak cyclogenesis months to explore their contributions. The analyses done using NCEP/NCAR Reanalysis-1 atmospheric fields, monthly O...

Eight super-pressure balloons floating at constant level between 50 and 80 hPa and three Infra-Red Montgolfier balloons of variable altitude (15 hPa daytime, 40– 80 hPa night time) have been launched at 22 S from Brazil in February–May 2004 in the frame of the HIBISCUS project. The flights lasted for 7 to 79 days residing mainly in the tropics, but some of them passed the tropical barrier and w...

The hypothalamic-pituitary-adrenal (HPA) axis plays an important role in sleep. Nevertheless, the association of sleep and its 24-h organization with negative feedback control of the HPA axis has received limited attention in population-based studies. We explored this association in 493 middle-aged persons of the Rotterdam Study, a large population-based study (mean age 56 years, standard devia...
