Revisiting ENSO/Indian Ocean Dipole phase relationships
Here we show that the characteristics of the Indian Ocean Dipole (IOD), such as its power spectrum and phase relationship with the El Nino-Southern Oscillation (ENSO), can be...- publication PDF

Eddy covariance VOC emission and deposition fluxes above grassland using PTR-TOF
Eddy covariance (EC) is the preferable technique for flux measurements since it is the only direct flux determination method. It requires a continuum of high time resolution...- publication PDF

An ensemble conditional nonlinear optimal perturbation approach: Formulation...
The conditional nonlinear optimal perturbation (CNOP) method proposed by Mu et al. (2003) has been a useful tool for studying predictability dynamics. Its further applications...- publication PDF

Local and downstream relationships between Labrador Sea water volume and...
While it has generally been understood that the production of Labrador Sea Water (LSW) impacts the Atlantic meridional overturning circulation (MOC), this relationship has not...- publication PDF

Construction and uncertainty estimation of a satellite-derived total...
Measurements of total precipitable water (TPW) from 11 satellite-borne microwave imaging radiometers are intercalibrated and merged into a single gridded monthly data set...- publication PDF

Factors influencing ice formation and growth in simulations of a mixed-phase...
In this paper, numerical simulations of an orographically induced wave cloud sampled in-situ during the ICE-L (Ice in Clouds Experiment - Layer clouds) field campaign are...- publication PDF

Revisiting the reanalysis-model discrepancy in Southern Hemisphere winter...
Southern Hemisphere (SH) storminess has increased in the satellite era and recent work suggests comprehensive climate models significantly underestimate the trend. Here, we...- publication PDF

The Decadal Climate Prediction Project (DCPP) contribution to CMIP6
The Decadal Climate Prediction Project (DCPP) is a coordinated multi-model investigation into decadal climate prediction, predictability, and variability. The DCPP makes use of...- publication PDF

Distribution and direct radiative forcing of carbonaceous and sulfate...
A multimode, two-moment aerosol model has been incorporated in the NCAR CAM3 to develop an interactive aerosol-climate model and to study the impact of anthropogenic aerosols on...- publication PDF

Spreading speed of magnetopause reconnection x-lines using ground-satellite...
Conceptual and numerical models predict that magnetic reconnection starts at a localized region and then spreads out of the reconnection plane. At the Earth's magnetopause this...- publication PDF

Ionospheric oscillations with a quasi-period of ∼6 hr during intense magnetic storms
We study the variations of the topside ionospheric ion density measured by Defense Meteorological Satellite Program satellites during the intense magnetic storm on 7-10 November...- publication PDF

Composite structure of tropopause polar cyclones
Tropopause polar vortices are coherent circulation features based on the tropopause in polar regions. They are a common feature of the Arctic, with typical radii less than 1500...- publication PDF

Observed 20th century desert dust variability: Impact on climate and biogeochemistry
Desert dust perturbs climate by interacting with incoming solar and outgoing long wave radiation, thereby changing precipitation and temperature, in addition to modifying ocean...- publication PDF

Is shallow convection sensitive to environmental heterogeneities?
The key assumption underlying convection parameterizations is that rising plumes develop in a horizontally homogeneous environment. With this in mind, we investigate the impact...- publication PDF

Downscaling extremes: A comparison of extreme value distributions in...
There is substantial empirical and climatological evidence that precipitation extremes have become more extreme during the twentieth century, and that this trend is likely to...- publication PDF
