Modeling land surface processes of the midwestern United States : predicting soil moisture under a warmer climate
… IBIS has several key advantages over the native surface physics scheme used in RegCM3, Biosphere-Atmosphere Transfer Scheme 1e (BATS1e), most notably superior subsurface hydrology and partitioning of runoff. A series of 22-year numerical experiments were completed to evaluate the ability of …

Mesoscale and stormscale ingredients of tornadic supercells producing long-track tornadoes in the 2011 Alabama super outbreak
… focuses on investigating the importance of surface moisture fluxes on influencing storm morphology. Three experimental simulations modifying various surface conditions were conducted, altering friction, surface fluxes and longwave radiation emission. Inflow soundings from these storms also …

Coupling of Integrated Biosphere Simulator to Regional Climate Model version 3
… model that includes representations of land surface processes, canopy physiology, vegetation phenology, terrestrial biogeochemistry, and vegetation dynamics. A single subroutine was created that allows RegCM3 to use IBIS instead of Biosphere-Atmosphere Transfer Scheme 1 e (BATS 1 e) for …

Friction under microscope with trapped ions in optical lattices
… can further be used to study quantum many-body physics of solids in periodic potentials, potentially relevant to friction and surface physics at the nanoscale and at cold surfaces.

Fundamental studies of the PVD technique.
… phase of both processes is addressed and the ion-surface interactions modelled using commercially available computer software. The improvement in adhesion on high speed steel is explained by sputtering of the substrate matrix leaving hard carbide particles standing proud of the surface. When …

Ultrafast Dynamics and Interactions During Growth at Surfaces
… technique capable of studying nanoscopic surface dynamics in thermal equilibrium. The energy resolution, which greatly exceeds that of alternative methods, makes it possible to probe motion on picosecond to nanosecond timescales. The present thesis is concerned with 3HeSE measurements and …

The role of interfacial and 'entropic' enzymes in transitory starch degradation : a mathematical modeling approach
… of the available area function - a concept from surface physics - to describe the adsorption step in the catalytic cycle. The method is applied to derive rate laws for two hydrolases, the Beta-amylase (BAM3) and the Isoamylase (DBE/ISA3), as well as to the Glucan, water dikinase (GWD) and a …

Land-atmosphere Exchange and Air Quality during Stable Atmospheric Boundary Layer Events
… the energy exchange at the interface of the surface and atmosphere, which impacts the ABL development. Thus, well-represented land-atmosphere exchange in numerical models is a perquisite for reliable meteorological predictability. A need for additional observations and numerical experiments …

Ultrahigh resolution surface phononics
… important quasiparticles in condensed matter physics; they influence a wide range of physical properties ranging from thermal and electrical conductivity to the propagation of sound. Phonons are also crucial to emerging research fields such as quantum information and superconductivity. This …

Scattering of aligned H₂ from Si(100)
… of freedom possessed by the reactants? In surface physics/chemistry the reaction under consideration is often unimolecular, i.e. the adsorption of a molecule onto or its desorption from some surface. In this case the participating degrees of freedom are the translation, vibration, and …

Helium Atom Scattering from Chiral Structures
… has been seldom applied to the study of chiral surfaces. The current thesis focuses on advancing the available theoretical and experimental tools to motivate the study of chiral surfaces using atomic beam techniques. The importance of chirality is discussed in chapter 1, along with the …

Modeling the impact of land surface feedbacks on post landfall tropical cyclones
<p>The land surface is an important component of numerical models. The land surface models are modules that control energy partitioning, compute surface exchange coefficients and form the only physical boundary in a regional scale numerical model. Thus, an accurate representation of land surface is …
