Simulating the MJO: Everybody Into the (Cold) Pool!

Aug 11, 2015 Funded By: ARM ASR

Most general circulation models (GCMs) continue to have difficulty simulating the Madden-Julian Oscillation (MJO), the most important source of tropical precipitation variability on time scales shorter than seasons. In recent years, evidence has grown for viewing the MJO as a “moisture mode.” Moisture modes differ from other equatorial waves in that they depend explicitly on [...]

Observed Relations Between Snowfall Microphysics and Triple-Frequency Radar Observations

Aug 05, 2015 Funded By: ARM ASR

Recent theoretical and observational studies indicated that triple-frequency measurements (e.g., combining Ku, Ka, and W band) bear the potential to derive important snowfall microphysical parameters like median mass diameter, fractal dimension, or particle habit. These observations further revealed that naturally occurring snowflakes exhibit scattering signatures that are in some cases consistent with spheroidal particle models [...]

Liquid Water the Key to Arctic Cloud Radiative Closure

Jul 21, 2015 Funded By: ARM ASR

Consistent with our growing understanding of Arctic liquid water clouds, it is not surprising that proper identification and characterization of cloud liquid water is important for accurately representing Arctic radiative fluxes. This conclusion is one of the primary findings resulting from the development and evaluation of a comprehensive cloud retrieval suite, called ShupeTurner, which is [...]

A Lidar View of Clouds in Southeastern China

Jul 15, 2015 Funded By: ARM ASR

From May 2008 to December 2009, a suite of instruments, including a micropulse lidar, were installed at a site along Lake Taihu, China, located in the center of the Yangtze Delta region. This was part of an effort to characterize aerosols, clouds, and their interactions in heavily polluted southeastern China. The seasonal patterns and diurnal [...]

ARM Data Used to Evaluate Reanalysis Results

Jul 06, 2015 Funded By: ARM ASR

Atmospheric reanalysis data sets have been used for a variety of applications, such as providing forcing data for single-column and cloud resolving models (Xie et al. 2004; Kennedy et al. 2011), investigating extreme weather and climatic events (Dong et al. 2011 and 2014), and examining forecast skill. These reanalysis data sets also provide an essential [...]
