Recent papers by the authors demonstrated the possible influence of initial errors of small amplitude and scale on the numerical prediction of the surprise'' snowstorm of 24 -...

Bulk ice-microphysical models parameterize the dynamic evolution of ice particles from advection, collection, and sedimentation through a cloud layer to the surface. Frozen...

Tropical cyclones are highly organized, rotating storms which rank among the most costly natural disasters in the United States. The processes which drive intensification and...

Direct eddy-covariance measurements of aerosol number fluxes obtained during the 2007 CHATS field experiment in Dixon, California, USA are compared with relaxed eddy...

We present a brief commentary on the landmark study of Exner (1913), in which an analysis of the correlation between monthly anomalies of "polar pressure" and sea level pressure...

As part of the Geoengineering Model Intercomparison Project a numerical experiment known as G6sulfur has been designed in which temperatures under a high-forcing future scenario...

A comparison of the impact of infrared (IR), microwave (MW), and radio occultation (RO) observations on NCEP's operational global forecast model over the month of March 2013 is...

Climate model simulations give a large range of over 100 years for predictions of when the Arctic could first become ice free in the summer, and many studies have attempted to...

Radar reflectivity factors exceeding 60 dBZ are documented within shallow (<3 km), warm (>0°C), summertime tropical rainbands offshore of the island of Hawaii. Dual-...

A regional atmospheric inversion method has been developed to determine the spatial and temporal distribution of CO2 sinks and sources across New Zealand for 2011-2013. This...

An update is provided on the Earth's global annual mean energy budget in the light of new observations and analyses. In 1997, Kiehl and Trenberth provided a review of past...

We present 9- and 7-day periodic oscillations in the global mean Total Electron Content (TEC) from 1 January 2005 to 31 December 2006. Spectral analysis indicates that the...

Global impact models represent process-level understanding of how natural and human systems may be affected by climate change. Their projections are used in integrated...

During the early‐to‐middle Miocene, global mean surface temperature (GMST) was approximately 8°C warmer than preindustrial, with a greater temperature increase...

To better understand variability in weather and climate, it is vital to address past atmospheric circulation. This need requires meteorological information not just from the...

Solar magnetic activity exhibits variations with periods between 1.5 and 4 years, the so-called quasi-biennial oscillations (QBOs), in addition to the well-known 11-year Schwabe...

A widely recognized issue found in most Earth System Models is that of convective precipitation being triggered too early during the day over land, often resulting in persistent...

The regional distributions of black carbon aerosol ( soot) are calculated and the impacts of black carbon aerosol on photolysis frequencies and ozone concentrations are...
