TL;DR: Relativistic viscous hydrodynamic fits to Brookhaven Rel ativistic Heavy Ion Collider data on the centrality dependence of multiplicity, transverse, and elliptic flow for square root s = 200 GeV Au+Au collisions seem to favor a much smaller viscosity over entropy ratio, below the bound from the anti-de Sitter conformal field theory conjecture.

TL;DR: The relativistic viscous fluid dynamics was formulated from first principles in an effective field theory framework, based entirely on the knowledge of symmetries and long-lived degrees of freedom.

TL;DR: In this paper, the authors analyzed the temporal and spatial variations of convection in South Asia using eight years of Tropical Rainfall Measuring Mission (TRMM) Precipitation Radar (PR) data and NCEP reanalysis fields.

TL;DR: In this article, eight years of Tropical Rainfall Measuring Mission (TRMM) Precipitation Radar (PR) data show how convective systems of different types contribute to precipitation of the South Asian monsoon.

TL;DR: Amesoscale convective systems (MCSs) as discussed by the authors are the principal rain-producing cloud systems over a region such as the upslope side of the Himalayas, and they can affect the rainstorms in two important ways: 1) Airflow over rising terrain may trigger new intense convective cells, thus revitalizing and maintaining the vigorous convective region of the MCS for a longer period of time; and 2) the orographic upward air motions may sustain and broaden the stratiform region of a MCS so that the gentler (but
