Recent intense hurricane response to global climate change
An Anthropogenic Climate Change Index (ACCI) is developed and used to investigate the potential global warming contribution to current tropical cyclone activity. The ACCI is...- publication PDF

Parallel implementations of ensemble data assimilation for atmospheric...
Numerical models are used to find approximate solutions to the coupled nonlinear partial differential equations associated with the prediction of the atmosphere. The model state...- publication PDF

A quest for effective hygroscopic cloud seeding
It is shown here that hygroscopic seeding requires two orders of magnitude more hygroscopic agent than can be delivered by flare technology for producing raindrop embryos in...- publication PDF

Wavelength-diverse polarization modulators for Stokes polarimetry
Information about the three-dimensional structure of solar magnetic fields is encoded in the polarized spectra of solar radiation by a host of physical processes. To extract...- publication PDF

First observations of short-period eastward propagating planetary waves from...
Unique Fe lidar observations in May 2014 at McMurdo, combined with Aura-Microwave Limb Sounder measurements, lead to a new discovery that the amplitudes of 4 day and 2.5 day...- publication PDF

Dependence of the high-latitude thermospheric densities on the...
The systematic analysis of the interplanetary magnetic field (IMF) By and Bz influences on observed thermospheric density is presented. For this purpose, the high-latitude...- publication PDF

Evaluation of a linear phase observation operator with CHAMP radio...
In this study a nonlocal, linear observation operator for assimilating radio occultation data is evaluated. The operator consists of modeling the excess phase, that is,...- publication PDF

Using TRMM latent heat as a source to estimate convection induced gravity...
Due to a lack of observations, it is a big challenge to quantify the momentum flux transported from the troposphere into the lower stratosphere by gravity waves generated by...- publication PDF

The whole atmosphere response to changes in the Earth's magnetic field from...
We study the effects of changes in the Earth's magnetic field between 1900 and 2000 on the whole atmosphere (0–500 km altitude), based on simulations with the Whole Atmosphere...- publication PDF

Satellite observations of the tropical terrestrial carbon balance and...
A constellation of satellites is now in orbit providing information about terrestrial carbon and water storage and fluxes. These combined observations show that the tropical...- publication PDF

Large estragole fluxes from oil palms in Borneo
During two field campaigns (OP3 and ACES), which ran in Borneo in 2008, we measured large emissions of estragole (methyl chavicol; IUPAC systematic name...- publication PDF

Intraannual variability of tides in the thermosphere from model simulations...
In this paper, we provide insights into limitations imposed by current satellite-based strategies to delineate tidal variability in the thermosphere, as well as the ability of a...- publication PDF

Characterizing changes in Eastern U.S. pollution events in a warming world
Risk assessments of air pollution impacts on human health and ecosystems would ideally consider a broad set of climate and emission scenarios, as well as natural internal...- publication PDF

Numerical simulations of the post-sunrise reorganization of a nocturnal...
A convection-permitting numerical model is used to simulate the post-sunrise reorganization of a nocturnal mesoscale convective system (MCS) observed over western and central...- publication PDF

Revisiting ENSO and IOD contributions to Australian precipitation
Tropical modes of variability, such as El Nino-Southern Oscillation (ENSO) and the Indian Ocean Dipole (IOD), exert a strong influence on the interannual variability of...- publication PDF

Trends in sunspots and North Atlantic sea level pressure
We analyze the periods 1878-1944 and 1944-2008. The quasi-stationary wave in the North Atlantic region was stronger and the baroclinity steeper in 1878-1944 than in 1944-2008....- publication PDF

Landsat near-infrared (NIR) band and ELM-FATES sensitivity to forest...
Forest disturbance and regrowth are key processes in forest dynamics, but detailed information on these processes is difficult to obtain in remote forests such as the Amazon. We...- publication PDF

Multiwavelet discontinuous Galerkin-accelerated Exact Linear Part (ELP)...
In this paper a new approach is presented to increase the time-step size for an explicit discontinuous Galerkin numerical method. The attributes of this approach are...- publication PDF

The substorm cycle as reproduced by global MHD models
Recently, Gordeev et al. (2015) suggested a method to test global MHD models against statistical empirical data. They showed that four community-available global MHD models...- publication PDF

The connected isotopic water cycle in the Community Earth System Model Version 1
Because of the pervasive role of water in the Earth system, the relative abundances of stable isotopologues of water are valuable for understanding atmospheric, oceanic, and...- publication PDF
