[1] Variability of the cloud population in the central equatorial Indian Ocean was observed in the context of the Madden-Julian Oscillation (MJO) during the Dynamics of the MaddenJulian Oscillation (DYNAMO) and Atmospheric Radiation Measurement Madden-Julian Investigation Experiment (AMIE) field campaigns. Radar observations from the polarimetric S-band radar on Addu Atoll in theMaldives charac...

The infralimbic (IL) cortex is importantly involved in regulating behavioral and physiological responses to stress, including those of the hypothalamic-pituitary-adrenal (HPA) axis. The mesocortical dopamine (DA) system is an important afferent modulator of this region, is highly stress sensitive and frequently shows functional hemispheric asymmetry. Postnatal handling stimulation facilitates d...

Abstract A spectral analysis of Great Plains 850-hPa meridional winds (V850) from ECMWF’s coupled climate reanalysis 1901–2010 (CERA-20C) reveals that their warm season (April–September) interannual variability peaks in May with 2–6-yr periodicity, suggestive an underlying teleconnection influence on low-level jets (LLJs). Using objective, dynamical jet classification framework based 500-hPa wa...

Employing reanalysis datasets, several threshold temperatures at 850 hPa are used tomeasure the wintertime [December–February (DJF)] areal extent of the lower-tropospheric, Northern Hemisphere, cold-air pool over the past 66 cold seasons. The analysis indicates a systematic contraction of the cold pool at each of the threshold temperatures. Special emphasis is placed on analysis of the trends i...

This study addresses the origin of the synoptic-scale disturbances that occur in the tropical western North Pacific ocean (WP) region in Northern Hemisphere summer. These have been called ‘‘easterly waves’’ and ‘‘tropical depression–type’’ (TD) disturbances. This analysis uses the National Center for Environmental Prediction–National Center for Atmospheric Research reanalysis dataset. By perfor...

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...

[1] We quantify the vertical velocity and upward mass flux in the tropical lower stratosphere on the basis of accurate radiative heating rate calculations using 8-year Southern Hemisphere Additional Ozonesondes balloon-borne measurements of temperature and ozone and cryogenic frost-point hygrometer measured water vapor in the tropics (15 S—10 N). The impact of tropospheric clouds on the stratos...

Dust is a common atmospheric phenomenon in Iran especially in central arid regions.  This severely affects environment as well as resident’s health. Among the results of this phenomenon are Respiratory diseases, bash radiation, accelerated soil erosion, Desertification and degradation of ecosystems. Some dusts are originated from local desert conditions but adjacency to neighboring countries de...
