Using ECWMF ERA-40 and Interim reanalysis data, the planetary wave fluxes associated with the February extreme stratospheric polar vortex were studied. Using the three-dimensional Eliassen-Palm (EP) flux as a measure of the wave activity propagation, the authors show that the unusual warm years in...
a, The polar displacement vector map (black arrows) corresponding to the (SrTiO3)10/(PbTiO3)10 superlattice in Fig. 2a is shown overlaid on the colourized (∇× PPD)[010]. b, A magnified view of the highlighted polar vortex shows the smooth rotation increasing towards a vortex core. ...

Interest in the distribution of black carbon (soot) aerosol (BCA) in the atmosphere is warranted for the following reasons: (1) BCA has the highest absorption cross section of any compound known, thus it can absorb solar radiation to cause atmospheric warming; (2) BCA is a strong adsorber ...

The polar vortex outbreak of February 2021 in the central United States provided an extreme test of such a node and gateway system for automatic data acquisition and telemetry to the internet over the cellular telephone network. The system, codesigned by USDA-ARS and Acclima, performed admirably ...

In particular, we will show that: (1) A well defined vortex wall, identified by an aerosol gradient, exist at ER-2 altitudes which is absent at DC-8 altitudes; (2) Pinatubo-enhanced aerosols are advected into the vortex from below; (3) Volcanic ash particles had accumulated near DC-8...
