[1] Changes in tropospheric water vapor over the Arctic are examined for the period 1979 to 2010 using humidity and temperature data from nine high latitude radiosonde stations north of 70 N with nearly complete records, and from six atmospheric reanalyses, emphasizing the three most modern efforts, MERRA, CFSR and ERA-Interim. Based on comparisons with the radiosonde profiles, the reanalyses a...

Based on the NECP/NCAR reanalysis dataset, associations between number of cold days (NCD) over East Asia (100–150° E, 25–55° N) and Arctic Oscillation (AO)/Arctic warming during 1956–2015 are explored. The results show NCD was closely associated with AO 1956–1990 1991–2015. It reveals showed a downward trend significantly negative correlation in previous stage, while it presented an upward nota...

This work aimed to identify the synoptic conditions associated with cold fronts (CFs) passage that causes intense winds in Santos Basin. Furthermore, atmospheric characteristics of CFs, which generated (INTW) and moderate (MODW) studied area, were identified. For this purpose, INTW MODW composites CFs episodes elaborated. First, cases selected from 10 m wind intensity observed buoy, belonging B...

As a neurotransmitter or neuromodulator, brain histamine has a variety of physiological roles in brain functions such as hypothalamic- pituitary- adrenal (HPA) activity. Histamine induces the release of ACTH through the activation of hypothalamic neurons containing vasopressin and CRH. Histamine induces the activity of HPA axis directly or indirectly. Endogenous opioids modulate the (HPA) axis ...
