Implications of Arctic sea ice changes for North Atlantic deep convection...
Using CCSM4 climate simulations for 1850-2300 with four different future forcing scenarios, we show that the maximum strength of the Atlantic meridional overturning circulation...- publication PDF

The COMBLE campaign: A study of marine boundary layer clouds in Arctic...
One of the most intense air mass transformations on Earth happens when cold air flows from frozen surfaces to much warmer open water in cold-air outbreaks (CAOs), a process...- publication PDF

Seasonal cycles of Oâ in the marine boundary layer: Observation and model...
We present a two-step approach for quantitatively comparing modeled and measured seasonal cycles of Oâ: (1) fitting sine functions to monthly averaged measurements and model...- publication PDF

A statistical analysis of the influence of deep convection on water vapor...
The factors that control the influence of deep convective detrainment on water vapor in the tropical upper troposphere are examined using observations from multiple satellites...- publication PDF

Recent warming of landfalling atmospheric rivers along the west coast of the...
Atmospheric rivers (ARs) often generate extreme precipitation, with AR temperature strongly influencing hydrologic impacts by altering the timing and magnitude of runoff. Long-...- publication PDF

Carbon dioxide physiological forcing dominates projected eastern Amazonian drying
Future projections of east Amazonian precipitation indicate drying, but they are uncertain and poorly understood. In this study we analyze the Amazonian precipitation response...- publication PDF

Doppler radar analysis of a tornadic miniature supercell during the landfall...
On 4 October 2015, a miniature supercell embedded in an outer rainband of Typhoon Mujigae produced a major tornado in Guangdong province of China, leading to 4 deaths and up to...- publication PDF
