A Multidimensional Characterization of MUIR Backscatter Spectra Resulting from Ionospheric Heating Experiments Performed at HAARP
<p>The results of several atmospheric heating experiments, which we performed at the HAARP facility, are presented. We sought to provide a multidimensional characterization of the various artificial ionospheric heating features by varying HF aspect angle, HF pump frequency, UHF pointing angle, and …

Radiative Forcing and Climatic Impact of the Mount Pinatubo Volcanic Eruption
Changes in radiative fluxes and atmospheric heating rates were computed by using the UIUC 24-layer Stratosphere/Troposphere General Circulation Model (ST-GCM) and a reconstructed dataset of the Pinatubo aerosol optical properties. Composite and the Singular Value Decomposition (SVD) analyses were …

The effect of the Agulhas Current on synthetic aperture radar derived wind fields
… of the current relative effect and SST-atmospheric heating for upcurrent wind directions results in a sharp increase in mean wind speeds over the inshore boundary of the current of between 5m/s and 7m/s (50−60%). Individual events can reach as high as 15m/s (100%) over 10′s of …

Microanalysis of impactors of the earth and impact products from the moon : the origin and evolution of micrometeorites, and tracking bombardment history through chemical and radioisotopic memories of lunar impact spherules
… study of micrometeorite petrography, chemistry, atmospheric alteration, and potential origin ensued. A classification system was developed with a focus on transitional internal textures to highlight the sequence of alteration occurring during atmospheric heating. Micrometeorite composition was …

Development of an accurate 3D Monte Carlo broadband atmospheric radiative transfer model
… spectrum (""MCBRaT-3D"" model) to produce heating rates relevant to atmospheric dynamics, and (3) developing tools to interface between the model and databases of single scattering properties of the real atmosphere. Special attention has been paid to practical aspects of implementation for …

Convective Dynamics of the Tropical Atmosphere in Three Idealized Approaches
Atmospheric convection organized at large spatial scales significantly influences precipitation patterns and weather events in tropical and subtropical regions, and has a rich, two-way interaction with Earth's climate. Tropical cyclones, mesoscale convective complexes, heat lows, and the rainbands …

Seasonal Variability of Heat and Mass Transport Process in the Upper Tropical Atlantic Ocean: A Numerical Model Study
… determined by the local heat balance between the atmospheric heating and the entrainment cooling. The model results suggested that the ITCZ movement is the primary cause of the net northward heat transport and its seasonal variation observed in the upper tropical Atlantic Ocean.</p>

Influence of high latitude anomalies on tropical climate phenomena and global climate
… role in global climate variability. The tropical atmospheric boundary layer is very sensitive to even small changes in the sea surface temperature (SST). Small SST anomalies in the tropics can lead to shifts in the large scale convection cells and result in atmospheric heating. There is potential …
