A nonoscillatory discontinuous Galerkin transport scheme on the cubed sphere
The discontinuous Galerkin (DG) method is high order, conservative, and offers excellent parallel efficiency. However, when there are discontinuities in the solution, the DG...- publication PDF

Block-structured adaptive meshes and reduced grids for atmospheric general...
Adaptive mesh refinement techniques offer a flexible framework for future variable-resolution climate and weather models since they can focus their computational mesh on certain...- publication PDF

A unifying polarization formalism for electric and magnetic multipole interactions
We extend the spherical tensorial formalism for polarization to the treatment of electric and magnetic multipole transitions of any order. We rely on the spherical-wave...- publication PDF

When will MISR detect rising high clouds?
It is predicted by both theory and models that high-altitude clouds will occur higher in the atmosphere as a result of climate warming. This produces a positive longwave...- publication PDF

Effects of dust aerosols on tropospheric chemistry during a typical...
This study examines the effect of a typical pre-monsoon season dust storm on tropospheric chemistry through a case study in northern India. Dust can alter photolysis rates by...- publication PDF

Floral advertisement scent in a changing plant-pollinators market
Plant-pollinator systems may be considered as biological markets in which pollinators choose between different flowers that advertise their nectar/pollen rewards. Although...- publication PDF

The impact of climate change on tribal communities in the US: Displacement,...
Tribal communities in the United States, particularly in coastal areas, are being forced to relocate due to accelerated rates of sea level rise, land erosion, and/or permafrost...- publication PDF

Dynamics of the intraseasonal oscillations of the Indian south equatorial current
The spatial and temporal features of intraseasonal oscillations in the southwestern Indian Ocean are studied by analyzing model simulations for the Indo-Pacific region. The...- publication PDF

Regime-oriented causal model evaluation of Atlantic-Pacific teleconnections in CMIP6
The climate system and its spatio-temporal changes are strongly affected by modes of long-term internal variability, like the Pacific decadal variability (PDV) and the Atlantic...- publication PDF

Recent warming of the southern Hemisphere subtropical lower stratosphere and...
Observed temperature changes from 2002 to 2022 reveal a pronounced warming of the Southern Hemisphere (SH) subtropical lower stratosphere, and a cooling of the Antarctic lower...- publication PDF

Aquaplanets, climate sensitivity, and low clouds
Cloud effects have repeatedly been pointed out as the leading source of uncertainty in projections of future climate, yet clouds remain poorly understood and simulated in...- publication PDF

Adaptively implicit MPDATA advection for arbitrary Courant numbers and meshes
Advection schemes with time step restrictions are widely used in weather and climate models. This can lead to instability in the presence of high flow speeds (relative to mesh...- publication PDF
