The NCAR Community Climate System Model (CCSM) finite-volume atmospheric core uses a C-D-grid discretization to solve the equations of motion. A linear analysis of this...

Using High Resolution Dynamic Limb Sounder observations and ERA-Interim reanalysis this study demonstrates that the warm conveyor belt (WCB) is a mechanism responsible for the...

Using 3 years worth of IASI (the Infrared Atmospheric Sounder Interferometer aboard METOP-A) measurements, we have identified 24 major events of uplift and transport of...

The Paleocene‐Eocene Thermal Maximum (PETM, ∼56 million years ago) is among the best‐studied climatic warming events in Earth history and is often compared to...

Massive Australian wildfires lofted smoke directly into the stratosphere in the austral summer of 2019/20. The smoke led to increases in optical extinction throughout the...

Regional convection-permitting model simulations of cloud populations observed during the 2011 Atmospheric Radiation Measurement (ARM) Madden-Julian Oscillation Investigation...

Nonlinear regression is a useful statistical tool, relating observed data and a nonlinear function of unknown parameters. When the parameter-dependent nonlinear function is...

Simulations by the Community Atmosphere Model (CAM) and 15 other climate models suggest that climate sensitivity is linked to continental middle to high latitude present-day...

The Amundsen Sea Low (ASL) is an important driver of Antarctic sea ice variations largely because of wind-driven sea ice and ocean transport anomalies. However, the nature of...

Aquatic ecologists are integrating mixotrophic plankton - here defined as microorganisms with photosynthetic and phagotrophic capacity - into their understanding of marine food...

The climate of the last two millennia was characterized by decadal to multicentennial variations, which were recorded in terrestrial records and had important societal impacts....

One of the major goals of the 2005 Antarctic Tropospheric Chemistry Investigation (ANTCI) was to bridge the information gap between current knowledge of South Pole (SP)...

We use in situ measurements of water vapor (H₂O), ozone (O₃), carbon dioxide (CO₂), carbon monoxide (CO), nitric oxide (NO), and total reactive nitrogen (NOy) obtained...

Between 15 and 17 March 2010, a workshop was held at Princeton University entitled 'Meeting a Grand Challenge to Hydrology: The Global Monitoring of Earth's Terrestrial Water'....

The Arctic radiation balance is strongly affected by clouds and surface albedo. Prior work has identified Arctic cloud liquid water path (LWP) and surface radiative flux biases...

The migrating diurnal tide is one of the dominant dynamical features in the low latitudes of the Earth's mesosphere and lower thermosphere (MLT) region, representing the...

Context. PG 1159-035 , a pre-white dwarf with Teff~140 000 K, is the prototype of both two classes: the PG 1159 spectroscopic class and the DOV pulsating class. Previous studies...

Accurate tropical cyclone (TC) track forecasts depend on having skillful numerical model predictions of the environmental wind field. Given that wind and temperature are related...

Many methods using ensemble integrations of prediction models as integral parts of data assimilation have appeared in the atmospheric and oceanic literature. In general, these...

Energetic electron precipitation (EEP) is an important source of polar nitrogen oxides (NOx) in the upper atmosphere. During winter, mesospheric NOx has a long chemical lifetime...
