Abstract. Part 1 (Ryoo et al., 2021) provided a climatological overview of the ObsErvation Aerosols above CLouds and their intEractionS (ORACLES) period assessed representativeness deployment years. In part 2, more detailed meteorological analyses support interpretation airborne measurements for aerosol transport its interaction with low clouds over southeastern (SE) Atlantic Ocean during Septe...

The Canadian Middle Atmosphere Model is used to examine the sensitivity of simulated climate to conservation of momentum in gravity wave drag parameterization. Momentum conservation requires that the parameterized gravity wave momentum flux at the top of the model be zero and corresponds to the physical boundary condition of no momentum flux at the top of the atmosphere. Allowing momentum flux ...

Cold air drainage and pooling occur in many mountain valleys, especially at night and during winter. Local climate regimes associated with frequent cold air pooling have substantial impacts on species phenology, distribution and diversity. However, little is known about how the degree and frequency of cold air drainage and pooling will respond to a changing climate. Evidence suggests that, beca...

Fractionation of stable isotopes in precipitation runs through the water cycle, and deuterium excess is a second-order parameter linking water-stable oxygen hydrogen isotopes. It strongly influenced by under-cloud evaporation unsaturated air, especially arid climates. Based on improved Stewart model, this study used 670 isotope data measured meteorological element from 11 sampling points Januar...

Tropical Storm Chantal during August 2001 was a storm that failed to intensify over the few days prior to making landfall on the Yucatan Peninsula. An observational study of Tropical Storm Chantal is presented using a diverse dataset including remote and in situ measurements from the NASA ER-2 and DC-8 and the NOAA WP-3D N42RF aircraft and satellite. The authors discuss the storm structure from...

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) chemically produce...

We describe a patient who developed transient and moderately severe thrombocytopenia (platelet count nadir 35 x 10(9)/L) after the transfusion of plasma. Using the technique of direct radioimmunoprecipitation, we showed that during the thrombocytopenia episode, the patient's platelets had IgG specifically bound to the glycoprotein (GP) Ia/IIa complex. Indirect radioimmunoprecipitation using ser...

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 patien...
