Abstract Based on observation and reanalysis datasets, numerical experiments with a simple dynamical model, climate model outputs, this study investigates the second leading waveguide teleconnection along summer polar front jet (PFJ) over Eurasia interannual time scale, British–Okhotsk Corridor (BOC) pattern. The BOC pattern explains 20.8% of total variance northern Eurasia, which is only sligh...

Using an external-cavity diode laser (ECDL) as the light source, we have observed the spectrum of CO(2) in the 1.5-µm atmospheric window including the (30(0)1)(I) <-- (00(0)0) and (31(1)1)(I) <-- (01(1)0)(I) bands. Good signal-to-noise ratio allowed us to lock the frequency of our ECDL to the absorption line centers. Wavenumber measurements of the transitions with accuracy about 6.6 x 10(-4) cm...

TheWalker circulation is linked to extratropical waves that are deflected from theNorthernHemisphere polar regions and travel southeastward over central Asia toward the western Pacific warm pool during northern winter. The wave pattern resembles the east Atlantic–west Russia pattern and influences the El Niño–Southern Oscillation (ENSO) region. A tripole pattern between theWest Siberian Plain a...

objective: the current study was undertaken to examine the bactericide effects of atmospheric plasma produced by flat and comb electrodes on e.coli. materials and methods: dc (20 w) and ac (500 w) power supplies, flat and comb electrodes, insulator and oxygen gas were used to produce atmospheric plasma. bactericide effects of the atmospheric plasma were studied on e.coli on sterilized plate pla...

Abstract A workshop on high-impact meteorological events in Italy was jointly organized by the newly formed Italia Meteo Agency (AIM) and Italian Association of Atmospheric Sciences Meteorology (AISAM) September 27, 2022. The aim to promote sharing experiences that all operational research centers have gained specific types events, favoring establishment a common know-how meteorology.

India's northward flight and collision with Asia was a major driver of global tectonics in the Cenozoic and, we argue, of atmospheric CO(2) concentration (pCO(2)) and thus global climate. Subduction of Tethyan oceanic crust with a carpet of carbonate-rich pelagic sediments deposited during transit beneath the high-productivity equatorial belt resulted in a component flux of CO(2) delivery to th...

despite the fact that hiv epidemic is mainly driven by injection drug use in iran, partners of people who inject drugs (pwid) have been seriously neglected in terms of effective preventive interventions. currently, sexual partners of pwid might have access to some harm reduction services at voluntary counselling and testing (vct) centers; however, their needs have not been effectively targeted ...

An important aspect of inevitable surprises, for the climate system, is potential occurrence compound extreme events. These can be events that occur at same time over geographic location or multiple locations within a given country around world. In this study, we investigate spatio-temporal variability summer hot and dry (CHD) European level quantify relationship between CHDs large-scale atmosp...

Abstract The Arctic continues to warm at a much faster rate than the global average. One process contributing “Arctic amplification” involves changes in low-frequency macroscale atmospheric circulation patterns and their consequent influence on regional climate. Here, using ERA5 data, we examine decadal impact of seven such winter near-surface temperature (SAT) precipitation (PPN) northern Russ...
