Thermal chains and entrainment in cumulus updrafts. Part I: Theoretical description
Recent studies have shown that cumulus updrafts often consist of a succession of discrete rising thermals with spherical vortex-like circulations. In this paper, a theory is...- publication PDF

Quantifying the effect of mixing on the mean age of air in CCMVal-2 and CCMI-1 models
The stratospheric age of air (AoA) is a useful measure of the overall capabilities of a general circulation model (GCM) to simulate stratospheric transport. Previous studies...- publication PDF

Attribution and impacts of upper ocean biases in CCSM3
The largest and potentially most important ocean near-surface biases are examined in the Community Climate System Model coupled simulation of present-day conditions. They are...- publication PDF

An algorithm for classification and outlier detection of time series data
An algorithm to perform outlier detection on time-series data is developed, the intelligent outlier detection algorithm (IODA). This algorithm treats a time series as an image...- publication PDF

Equatorial plasma bubbles developing around sunrise observed by an all-sky...
A large number of studies have shown that equatorial plasma bubbles (EPBs) occur mainly after sunset, and they usually drift eastward. However, in this paper, an unusual EPB...- publication PDF

Twenty-first-century arctic climate change in CCSM4
The authors summarize the twenty-first-century Arctic climate simulated by NCAR’s Community Climate System Model, version 4 (CCSM4). Under a strong radiative forcing scenario,...- publication PDF

Ash particles detected in the tropical lower stratosphere
We report here on measurements of relatively large (up to ≃5‐μm maximum dimension) particles detected in the tropical western Pacific lower stratosphere. The particles were...- publication PDF
