Polar vortices are a common feature in the solar system, but their structure varies between planets. Although polar vortices are characterized by a coherent region of high potential vorticity (PV) in the polar regions, the meridional variation of PV ...

Detection of air within the northern hemisphere polar vortex at Wakkanai and at Tsukuba, Japan [PDF]
P(論文)Intensive ozonesonde observations were conducted at Wakkanai(45.4°N , 141.7°E ), the northernmost city of Japan, during the period 15th to 24th February 2001.

Protocol for quantifying miRNA trafficking across the endosomal membrane
An in vitro protocol measures miRNA uptake into endosomes isolated from mammalian cell extracts, which are free of subcellular contaminants. Performed at 37 °C in the presence of ATP, it ensures the import of single‐stranded miRNA into the endosomal lumen.

We use Aura Microwave Limb Sounder (MLS) trace gas measurements to investigate whether water vapor (H2O) injected into the stratosphere by the Hunga Tonga‐Hunga Ha'apai (HTHH) eruption affected the 2022 Antarctic stratospheric vortex.

Ozone and water vapour in the austral polar stratospheric vortex and sub-vortex [PDF]
Abstract. In-situ measurements of ozone and water vapour, in the Antarctic lower stratosphere, were made as part of the APE-GAIA mission in September and October 1999. The measurements show a distinct difference above and below the 415K isentrope. Above 415K, the chemically perturbed region of low ozone and water vapour is clearly evident.

Arctic polar vortex dynamics during winters 2014/2015 and 2020/2021 [PDF]
The dynamic barrier of the polar vortex contributes to lowering the temperature inside the vortex in the lower stratosphere and prevents the penetration of air masses into the vortex. The presence of a dynamic barrier during winter is one of the criteria

In this study, a novel esterase from the thermoacidophilic archaeon Thermoplasma acidophilum was biochemically and structurally characterized. Our results demonstrate that Ta0887 is a highly thermostable esterase that preferentially hydrolyzes p‐nitrophenyl hexanoate and possesses an α‐helical cap domain that likely contributes to its substrate ...

Climatology and trends in the forcing of the stratospheric zonal-mean flow [PDF]
The momentum budget of the Transformed Eulerian-Mean (TEM) equation is calculated using the European Centre for Medium-Range Weather Forecasts (ECMWF) reanalysis (ERA-40) and the National Centers for Environmental Prediction (NCEP) Reanalysis 2 (R-2 ...
