Thermal Circulation Patterns and Turbulent Fluxes along Steep Mountain Slopes

Wolf Hendrik Huwald, Marc Parlange, Chad Higgins, Eric Richard Pardyjak, Daniel Nadeau, Fabian Bärenbold

In hydrology, it is crucial to understand the atmospheric flow dynamics in mountainous terrain to predict turbulent exchanges of heat and moisture accurately at the regional scale. Under clear skies and weak synoptic conditions, these land–atmosphere inter ...

Model of an Interdigitated Microsensor to Detect and Quantify Cells Flowing in a Test Chamber

Carlotta Guiducci, Elena Bianchi, Federica Boschetti

A finite elements model of an interdigitated microsensor has been used to investigate the sensitivity of the sensor to the detection and the quantification of cells flowing in a test chamber. In particular the sensitivity of the sensor towards the geometry ...

Collisional damping of zonal flows due to finite Larmor radius effects

Paolo Ricci

The collisional damping of seeded E X B zonal flows on the ion Larmor radius scale is studied using a gyrokinetic model. The focus is on flow damping due to finite Larmor radius effects, which cause a nu(parallel to)/nu anisotropy of the ion distribution f ...

On uncertainty estimates of crystallographic quantities including cell-parameter uncertainties

Dieter Schwarzenbach

In a recent publication, Haestier [J. Appl. Cryst. (2009), 42, 798-809] has proposed a method to take care of the unit-cell-parameter uncertainties in the calculation of geometric quantities such as interatomic distances and bond angles by modifying the un ...

Sensitivity of boreal-summer circulation and precipitation to atmospheric aerosols in selected regions-Part 1: Africa and India

Athanasios Nenes, Yao Zhou

Version-4 of the Goddard Earth Observing System (GEOS-4) General Circulation Model (GCM) was employed to assess the influence of potential changes in aerosols on the regional circulation, ambient temperatures, and precipitation in four selected regions: In ...

Automated Raman Lidar for Day and Night Operational Observation of Tropospheric Water Vapor for Meteorological Applications

Todor Dinoev

Water vapor is a fundamental constituent of the atmosphere and is the most abundant green house gas thus having an important influence on climate. It is as well a key prognostic variable for numerical weather prediction models (NWP). Currently, the vertica ...

Orbital forcing and the role of the Latitudinal Temperature/Isolation Gradient

Basil Andrew Stansfield Davis

Orbital forcing of the climate system is clearly shown in the Earths record of glacial–interglacial cycles, but the mechanism underlying this forcing is poorly understood. Traditional Milankovitch theory suggests that these cycles are driven by changes in ...

Distinct CCN activation kinetics above the marine boundary layer along the California coast

Athanasios Nenes

The influence of aerosols on cloud properties remains one of the largest sources of uncertainty in estimates of the anthropogenic component of climate change. Here we report the rate of cloud droplet formation on particles sampled at a site near the Califo ...

Parameterization of cloud droplet formation for global and regional models: Including adsorption activation from insoluble CCN

Athanasios Nenes

Dust and black carbon aerosol have long been known to exert potentially important and diverse impacts on cloud droplet formation. Most studies to date focus on the soluble fraction of these particles, and overlook interactions of the insoluble fraction wit ...
