The light-wind, clear-sky, very stable boundary layer (vSBL) is characterized by large values of bulk
Richardson number. The light winds produce weak shear, turbulence, and mixing, and resulting strong
temperature gradients near the surface. Here...

A mesoscale atmospheric model is used to address the characteristics of stratified flow bounded by a side
wall along a varying coastline. Initial Froude number values are varied through alteration of marine inversion
strength, permitting...

Ship tracks appearing in both the morning and afternoon Moderate Resolution Imaging Spectroradiometer
(MODIS) imagery for the Pacific Ocean off the west coast of the United States were used to study the
morning-to-afternoon evolution of marine...

The 1-km advanced very high resolution radiometer observations from the morning, NOAA-12, and afternoon,
NOAA-11, satellite passes over the coast of California during June 1994 are used to determine the altitudes,
visible optical depths, and cloud...

One-kilometer Advanced Very High Resolution Radiometer (AVHRR) observations of the effects of ships on
low-level clouds off the west coast of the United States are used to derive limits for the degree to which clouds
might be altered by increases...

The initiation of ice in an isolated orographic wave cloud was compared with expectations based on ice
nucleating aerosol concentrations and with predictions from new ice nucleation parameterizations applied in
a cloud parcel model. Measurements...

This paper presents a detailed study of a single thunderstorm anvil cirrus cloud measured on 21 July 2002
near southern Florida during the Cirrus Regional Study of Tropical Anvils and Cirrus Layers–Florida Area
Cirrus Experiment (CRYSTAL-FACE)....

This two-part study attempts to find appropriate mass dimension and terminal velocity relationships that,
when considered together with particle size distributions (PSD), agree with coincident measurements of ice
water content (IWC), and with...

The mixing lengths for heat and momentum are computed from seven levels of eddy correlation data during
the Cooperative Atmosphere–Surface Exchange Study-1999 (CASES-99). A number of formulations of the
mixing length are evaluated, including...

The growth of linear disturbances to stable and unstable time-periodic basic states is analyzed in an asymptotic
model of weakly nonlinear, baroclinic wave–mean interaction. In this model, an ordinary differential equation
for the wave amplitude...

The local predictability of the El Nin˜o–Southern Oscillation (ENSO) is examined by the analysis of the
evolution of small disturbances to an unstable 4.3-yr ENSO cycle in the Cane–Zebiak model forced by perpetual
July conditions. The 4.3-yr cycle...
