Pan-Antarctic analysis aggregating spatial estimates of Adélie penguin...
Colonially-breeding seabirds have long served as indicator species for the health of the oceans on which they depend. Abundance and breeding data are repeatedly collected at...- publication PDF

Revisiting the relationship between jet position, forced response, and...
Climate models exhibit a wide range in latitudinal position of the Southern Hemisphere westerly jet. Previous work has demonstrated, in the annual mean, that models with lower...- publication PDF

Historical and future vegetation changes in the degraded frozen soil and the...
About 99% of the Tibetan Plateau (TP) is covered by frozen soils and degradation of frozen soils will certainly impact TP's ecosystems. Here, we investigate decadal changes of...- publication PDF

Carbon dioxide trends in the mesosphere and lower thermosphere
We investigated trends of carbon dioxide (CO2) in the upper atmosphere, using data from the Atmosphere Chemistry Experiment Fourier Transform Spectrometer and from the Sounding...- publication PDF

Potential role of the ocean thermostat in determining regional differences...
Several negative feedback mechanisms have been proposed by others to explain the stability of maximum sea surface temperature (SST) in the western Pacific warm pool (WPWP). If...- publication PDF

High-resolution polarimetric radar observations of snow-generating cells
High-resolution X-band polarimetric radar data were collected in 19 snowstorms over northern Colorado in early 2013 as part of the Front Range Orographic Storms (FROST) project....- publication PDF

The influence of mixing on the stratospheric age of air changes in the 21st century
Climate models consistently predict an acceleration of the Brewer-Dobson circulation (BDC) due to climate change in the 21st century. However, the strength of this acceleration...- publication PDF

Emergence of magnetic flux generated in a solar convective dynamo. I. The...
We present a realistic numerical model of sunspot and active region formation based on the emergence of flux bundles generated in a solar convective dynamo. To this end, we use...- publication PDF

Uncertainties of estimates of inertio-gravity energy in the atmosphere. Part...
This paper analyzes the spectra and spatiotemporal features of the large-scale inertia-gravity (IG) circulations in four analysis systems in the tropics. Of special interest is...- publication PDF

Predicted chance that global warming will temporarily exceed 1.5 °C
The Paris Agreement calls for efforts to limit anthropogenic global warming to less than 1.5 degrees C above preindustrial levels. However, natural internal variability may...- publication PDF

Analysis of a dryline during IHOP: Implications for convection initiation
A detailed analysis of a dryline that formed on 22 May 2002 during the International HâO Project (IHOP) is presented. The dryline was classified as a null case since air...- publication PDF

The mean climate of the Community Atmosphere Model (CAM4) in forced SST and...
The Community Atmosphere Model, version 4 (CAM4), was released as part of the Community Climate System Model, version 4 (CCSM4). The finite volume (FV) dynamical core is now the...- publication PDF
