Tropospheric rivers? – A pilot study

TLDR
In this article, the presence of a filamentary structure has been detected in daily global tropospheric water vapor flux values, where the filamentary structures have lengths many times their widths and persist for many days while being translated through the atmosphere.
Abstract
Computations of daily global tropospheric water vapor flux values show the presence of a filamentary structure The filaments, here called rivers, have lengths many times their widths and persist for many days while being translated through the atmosphere They are present in data analyzed for both 1981 and 1991 The water vapor flux maxima coincide quite closely to reflectivity features (averaged from wavelengths of 380 and 360 nm) as revealed by the Total Ozone Mapping Spectrometer (TOMS) It is suggested that the filamentary structure may also be present in other trace constituents

A Proposed Algorithm for Moisture Fluxes from Atmospheric Rivers

TL;DR: In this paper, a new algorithm is applied to study water vapor fluxes in the troposphere using wind and moisture data from the European Centre for Medium-Range Weather Forecasts.

A lagrangian‐based analysis of extratropical cyclones. I: The method and some applications

TL;DR: A Lagrangian-based method of analysis is introduced to examine the space-time structure and dynamics of extratropical cyclogenesis and can provide a qualitative depiction of, quantitative information about, and dynamical insight into, key features of mid-latitude cyclones.

Satellite and CALJET Aircraft Observations of Atmospheric Rivers over the Eastern North Pacific Ocean during the Winter of 1997/98

TL;DR: The authors used a unique combination of airborne and satellite observations to characterize narrow regions of strong horizontal water vapor flux associated with polar cold fronts that occurred over the eastern North Pacific Ocean during the winter of 1997/98.

Orographic effects on precipitating clouds

TL;DR: In this article, it was shown that mesoscale convective systems are triggered by nocturnal downslope flows and by diurnally triggered disturbances propagating away from mountain ranges.

Oceanic and terrestrial sources of continental precipitation

TL;DR: The most important sources of atmospheric moisture at the global scale are identified, both oceanic and terrestrial, and a characterization is made of how continental regions are influenced by water from different moisture source regions as discussed by the authors.

Stratospheric-Tropospheric Exchange Based on Radioactivity, Ozone and Potential Vorticity

TL;DR: In this paper, the authors compared both discrete and continuous measurements of radioactivity made during Project Springfield and found a positive correlation between potential vorticity and radioactivity of stratospheric origin.

Intermittent vortex structures in homogeneous isotropic turbulence

TL;DR: In contrast to the classical description of turbulence as an array of 'pancake'- or 'lasagne'-like eddies, this article found that high-amplitude vortex structures are tube-like and that they generate local velocity fields that spiral around them.

Structure of stratospheric intrusions into the troposphere

Christof Appenzeller, +1 more
- 13 Aug 1992 - 
TL;DR: In this paper, the authors combine satellite measurements with data from a weather prediction model to show that fine-scale structure can be resolved in intrusions of stratospheric air into the troposphere.

Studies on the General Development of Motion in a Two‐Dimensional, Ideal Fluid

TL;DR: In this article, the authors discuss qualitatively certain kinds of asymptotic motion in a two-dimensional, ideal fluid by help of methods of statistical mechanics and stress that the final development of such a fluid cannot be adequately described by use of the ordinary equations of motion, but that a coarse grain representation should be used.

The Band Structure of the Atmosphere

Joachim P. Kuettner
- 01 Aug 1959 - 
TL;DR: In this article, the typical vertical curvature was found to be 10 −7 (cm −1 sec −1 ) with a curved velocity profile of a rather uniform direction, which is similar to the curvature of cloud bands.
