RISCharacterization of Three-Mode Combination Internal Resonances in Electrostatically Actuated Flexible–Flexible Microbeams
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Nonlinear intermodal coupling based on internal resonances in MEMS resonators has advanced significantly over the past two decades for various real-world applications. In this study, we demonstrate the existence of various ...
Precipitation Recycling Variability and Ecoclimatological Stability—A Study Using NARR Data. Part I: Central U.S. Plains Ecoregion
Publisher: American Meteorological Society
Abstract: Precipitation recycling is one of the key mechanisms linking the land surface and atmospheric dynamics. This work explores the physical mechanisms that modulate precipitation recycling variability at the daily-to-intraseasonal ...
A Modeling Study of the ENSO Influence on the Terrestrial Energy Profile in North America
Publisher: American Meteorological Society
Abstract: The influence of the El Niño?Southern Oscillation (ENSO) on the terrestrial energy profile over North America is studied using a 15-yr model simulation. A large-area basin scale (LABs) land surface model is driven using ...
Role of Terrestrial Hydrologic Memory in Modulating ENSO Impacts in North America
Publisher: American Meteorological Society
Abstract: Relationships among the terrestrial hydrologic processes over the North American continent associated with the El Niño?Southern Oscillation (ENSO) are investigated using a large-area basin-scale land surface model driven ...
Dominant Modes of Moisture Flux Anomalies over North America
Publisher: American Meteorological Society
Abstract: This study investigates the principal modes of seasonal moisture flux transport over North America, analyzing their possible dependence on large-scale atmospheric circulation patterns. It uses 23 yr (1979?2001) of 6-hourly ...
Topographic Influence on the Seasonal and Interannual Variation of Water and Energy Balance of Basins in North America
Publisher: American Meteorological Society
Abstract: A large area basin-scale (LABs) hydrologic model is developed for regional, continental, and global hydrologic studies. The heterogeneity in the soil-moisture distribution within a basin is parameterized through the ...
NVAP and Reanalysis-2 Global Precipitable Water Products : Intercomparison and Variability Studies
Publisher: American Meteorological Society
Abstract: In this study similarities and differences between NASA's Water Vapor Project (NVAP) and NCEP?NCAR's reanalysis-2 total precipitable water (TPW) datasets are investigated, along with an assessment of its space?time ...
A New Look at Rainfall Fluctuations and Scaling Properties of Spatial Rainfall Using Orthogonal Wavelets
Publisher: American Meteorological Society
Abstract: It has been observed that the finite-dimensional distribution functions of rainfall cannot obey simple scaling laws due to rainfall intermittency (mixed distribution with an atom at zero) and the probability of rainfall ...
Characterizing Multiscale Variability of Zero Intermittency in Spatial Rainfall
Publisher: American Meteorological Society
Abstract: In this paper the authors study how zero intermittency in spatial rainfall, as described by the fraction of area covered by rainfall, changes with spatial scale of rainfall measurement or representation. A statistical ...
A Changing Climatology of Precipitation Persistence across the United States Using Information-Based Measures
Publisher: American Meteorological Society
Abstract: AbstractThe sequencing, or persistence, of daily precipitation influences variability in streamflow, soil moisture, and vegetation states. As these factors influence water availability and ecosystem health, it is important ...
