RISValidation of a Long-Range Trajectory Model Using Gas Balloon Tracks from the Gordon Bennett Cup 95
Publisher: American Meteorological Society
Abstract: In September 1995, 18 gas balloon teams competed at the Gordon Bennett Cup, a long-distance ballooning event. The landing positions, travel times of all teams, and detailed information on the tracks of four teams are ...
A Lagrangian Analysis of the Atmospheric Branch of the Global Water Cycle. Part II: Moisture Transports between Earth’s Ocean Basins and River Catchments
Publisher: American Meteorological Society
Abstract: A diagnostic Lagrangian method to trace the budgets of freshwater fluxes, first described in Part I of this article, is used here to establish source?sink relationships of moisture between earth?s ocean basins and river ...
A Lagrangian Analysis of the Atmospheric Branch of the Global Water Cycle. Part I: Method Description, Validation, and Demonstration for the August 2002 Flooding in Central Europe
Publisher: American Meteorological Society
Abstract: Understanding and quantifying the relationships between evaporation of water in one region, precipitation in another, and the transport processes connecting them, is one of the key problems in hydrometeorology. However, ...
Moisture Origin and Meridional Transport in Atmospheric Rivers and Their Association with Multiple Cyclones
Publisher: American Meteorological Society
Abstract: uring December 2006 many cyclones traveled across the North Atlantic, causing temperature and precipitation in Norway to be well above average. Large excursions of high vertically integrated water vapor, often referred to ...
Parameterization of Convective Transport in a Lagrangian Particle Dispersion Model and Its Evaluation
Publisher: American Meteorological Society
Abstract: This paper presents the revision and evaluation of the interface between the convective parameterization by Emanuel and ?ivkovi?-Rothman and the Lagrangian particle dispersion model ?FLEXPART? based on meteorological data ...
Interpolation Errors in Wind Fields as a Function of Spatial and Temporal Resolution and Their Impact on Different Types of Kinematic Trajectories
Publisher: American Meteorological Society
Abstract: This paper discusses some of the uncertainties that influence kinematic trajectory calculations. The interpolation errors due to different interpolation schemes are examined by degrading high-resolution wind fields from a ...
Input Data Requirements for Lagrangian Trajectory Models
Publisher: American Meteorological Society
Abstract: r 2011 an American Geophysical Union Chapman Conference was held in Grindelwald, Switzerland, titled ?Advances in Lagrangian Modeling of the Atmosphere.? Lagrangian models are being applied to a wide range of high-impact ...
A 15-Year Climatology of Warm Conveyor Belts
Publisher: American Meteorological Society
Abstract: This study presents the first climatology of so-called warm conveyor belts (WCBs), strongly ascending moist airstreams in extratropical cyclones that, on the time scale of 2 days, rise from the boundary layer to the upper ...
Diagnostic Downscaling of Large-Scale Wind Fields to Compute Local-Scale Trajectories
Publisher: American Meteorological Society
Abstract: This paper describes a simple method, based on routine meteorological data, to produce high-resolution wind analyses throughout the planetary boundary layer (PBL). It is a new way to interpolate wind measurements. According ...
A New Perspective of Stratosphere–Troposphere Exchange
Publisher: American Meteorological Society
Abstract: Stratosphere?troposphere exchange (STE) is important for the chemical composition of both the stratosphere and troposphere. Modifications of STE in a changing climate may affect stratospheric ozone depletion and the oxidizing ...
