Synthesis of Observations from the Precision Atmosphere Marine Boundary Layer Experiment (PreAMBLE)
(American Meteorological Society, 2017-05-22)Research flights during the Precision Atmospheric Marine Boundary Layer Experiment (PreAMBLE) in Southern California during May–June 2012 focused on three main features found in the nearshore marine boundary layer (MBL): ... -
Meteorological Interpretation of Orographic Precipitation Gradients along an Andes West SLope Basin at 30°S (Elqui Valley, Chile)
(American Meteorological Society, 2017-02-24)To better forecast streamflow and water resource availability, it is important to have an understanding of the meteorological drivers of the orographic precipitation gradient (OPG), especially critical in semiarid mountainous ... -
An Atmospheric Hydraulic Jump in the Santa Barbara Channel
(American Meteorological Society, 2017-11-14)As part of the Precision Atmospheric Marine Boundary Layer Experiment, the University of Wyoming King Air sampled an atmospheric environment conducive to the formation of a hydraulic jump on 24 May 2012 off the coast of ... -
Understanding watershed hydrogeochemistry: 2. Synchronized hydrological and geochemical processes drive stream chemostatic behavior
(American Geophysical Union, 2017-03-23)Why do solute concentrations in streams remain largely constant while discharge varies by orders of magnitude? We used a new hydrological land surface and reactive transport code, RT‐Flux‐PIHM, to understand this long‐standing ... -
Use of Cloud Radar Doppler Spectra to Evaluate Stratocumulus Drizzle Size Distributions in Large-Eddy Simulations with Size-Resolved Microphysics
(American Meteorological Society, 2017-12)A case study of persistent stratocumulus over the Azores is simulated using two independent large-eddy simulation (LES) models with bin microphysics, and forward-simulated cloud radar Doppler moments and spectra are compared ... -
Assessing the Roles of Fire Frequency and Precipitation in Determining Woody Plant Expansion in Central U.S. Grasslands
(American Geophysical Union, 2017-10-05)Woody plant expansion into grasslands and savannas is occurring and accelerating worldwide and often impacts ecosystem processes. Understanding and predicting the environmental and ecological impacts of encroachment has ... -
Demand pull or supply push? Metro-level analysis of start-ups in the United States
(Taylor & Francis, 2017)This paper examines factors related to higher regional start-up activity. Two hypotheses are formulated to explain start-ups: the demand-pull hypothesis argues that the amount, growth and density of aggregate demand will ... -
The Time Scales of Variability of Marine Low Clouds
(American Meteorological Society, 2016-09-15)Multidecade global regressions of inversion strength, vertical velocity, and sea surface temperature (SST) on low cloud amount, from subdaily to multiyear time scales, refute the dominance of seasonal inversion strength ... -
Life Cycle Characteristics of Warm-Season Severe Thunderstorms in Central United States from 2010 to 2014
(MDPI, 2016-09-08)Weather monitoring systems, such as Doppler radars, collect a high volume of measurements with fine spatial and temporal resolutions that provide opportunities to study many convective weather events. This study examines ... -
Impact of Sensor Zenith Angle on MOD10A1 Data Reliability and Modification of Snow Cover Data for the Tarim River Basin
(MDPI, 2016)Snow in the mountainous watersheds of the Tarim River Basin is the primary source of water for western China. The Snow Cover Daily L3 Global 500-m Grid (MOD10A1) remote sensing dataset has proven extremely valuable for ... -
Aircraft Measurements and Numerical Simulations of an Expansion Fan off the California Coast
(American Meteorological Society, 2016-09-12)Mountains along the California coastline play a critical role in the dynamics of marine atmospheric boundary layer (MBL) airflow in the vicinity of the shoreline. Large changes in the MBL topology have been known to occur ... -
Use of MODIS Sensor Images Combined with Reanalysis Products to Retrieve Net Radiation in Amazonia
(MDPI, 2016-07-16)In the Amazon region, the estimation of radiation fluxes through remote sensing techniques is hindered by the lack of ground measurements required as input in the models, as well as the difficulty to obtain cloud-free ... -
Warm spring reduced carbon cycle impact of the 2012 US summer drought
(National Academy of Sciences, 2016-05-24)The global terrestrial carbon sink offsets one-third of the world’s fossil fuel emissions, but the strength of this sink is highly sensitive to large-scale extreme events. In 2012, the contiguous United States experienced ... -
The sensitivity of carbon exchanges in Great Plains grasslands to precipitation variability
(American Geophysical Union, 2016-02-02)In the Great Plains, grassland carbon dynamics differ across broad gradients of precipitation and temperature, yet finer-scale variation in these variables may also affect grassland processes. Despite the importance of ... -
Land Change Regimes and the Evolution of the Maize-Cattle Complex in Neoliberal Mexico
(MDPI, 2015-08-21)How globalization impacts native land cover has become an important issue in studies addressing environmental change, which draw explicit attention to processes of cause and effect operating over significant distances. The ... -
Glaciological and marine geological controls on terminus dynamics of Hubbard Glacier, southeast Alaska
(American Geophysical Union, 2015-06-25)Hubbard Glacier, located in southeast Alaska, is the world's largest nonpolar tidewater glacier. It has been steadily advancing since it was first mapped in 1895; occasionally, the advance creates an ice or sediment dam ... -
Landscape heterogeneity drives contrasting concentration–discharge relationships in shale headwater catchments
(Published by Copernicus Publications on behalf of the European Geosciences Union (EGU)., 2015-08-03)Solute concentrations in stream water vary with discharge in patterns that record complex feedbacks between hydrologic and biogeochemical processes. In a comparison of three shale-underlain headwater catchments located in ... -
Two methods for estimating limits to large-scale wind power generation
(Proceedings of the National Academy of Sciences of the United States of America, 2015-06-25)Wind turbines remove kinetic energy from the atmospheric flow, which reduces wind speeds and limits generation rates of large wind farms. These interactions can be approximated using a vertical kinetic energy (VKE) flux ... -
