AN INVESTIGATION OF REMOTELY SENSED URBAN HEAT ISLAND CLIMATOLOGY
(University of Kansas, 2014-08-31)Satellite remotely sensed temperatures are widely used for urban heat island (UHI) studies. However, the abilities of satellite surface and atmospheric data to assess the climatology of UHI face many unknowns and challenges. ... -
How can we use MODIS land surface temperature to validate long-term urban model simulations?
(American Geophysical Union, 2014-03-27)High spatial resolution urban climate modeling is essential for understanding urban climatology and predicting the human health impacts under climate change. Satellite thermal remote-sensing data are potential observational ... -
Evaluating the impact of urban morphology configurations on the accuracy of urban canopy model temperature simulations with MODIS
(American Geophysical Union, 2014-06-09)Simulations of the urban environment contribute to assessments of current and future urban vulnerabilities to extreme heat events. The accuracy of simulations of the urban canopy can be degraded by inaccurate or oversimplified ... -
Multiscale Interactions between Water and Carbon Fluxes and Environmental Variables in A Central U.S. Grassland
(MDPI, 2013-04-10)The temporal interactions between water and carbon cycling and the controlling environmental variables are investigated using wavelets and information theory. We used 3.5 years of eddy covariance station observations from ... -
The Effects of Great Plains Irrigation on the Surface Energy Balance, Regional Circulation, and Precipitation
(American Geophysical Union, 2014-05-05)Irrigation provides a needed source of water in regions of low precipitation. Adding water to a region that would otherwise see little natural precipitation alters the partitioning of surface energy fluxes, the evolution ... -
Restructuring and the Nonmetropolitan Turnaround: The California Evidence
(University of Hawaii Press, 1986-01-01)Conceptions of nonmetropolitan growth have rarely benefited from current debates in social theory. An analytical interpretation of the literature on the "turnaround" is offered from a structuralist perspective. In this ... -
On the Forecasting of Orogenic Mesoscale Convective Complexes
(American Meteorological Society, 1999-12-01)Evidence is presented to support the hypothesis that mesoscale convective complexes (MCCs) near the Rocky Mountains are more likely to form when the middle-tropospheric relative humidity is greater than average and the ... -
The Generation of a Mesoscale Convective System from Mountain Convection
(American Meteorological Society, 1999-06-01)A mesoscale convective system (MCS) that formed just to the east of Denver is investigated with a nonhydrostatic numerical model to determine which processes were important in its initiation. The MCS developed from outflow ... -
Flow over Heated Terrain. Part I: Linear Theory and Idealized Numerical Simulations
(American Meteorological Society, 2005-09-01)The flow past heated topography is examined with both linear and nonlinear models. It is first shown that the forcing of an obstacle with horizontally homogenous surface heating can be approximated by the forcing of an ... -
Flow over Heated Terrain. Part II: Generation of Convective Precipitation
(American Meteorological Society, 2005-09-01)Previous studies have shown that thunderstorms in the Rocky Mountain region have preferred areas in which to form. There has been some indication that these areas depend on the midtropospheric wind direction. A nonhydrostatic ... -
Diurnal Precipitation Variations in South-Central New Mexico
(American Meteorological Society, 1993-07-01)Orographic forcing of diurnal precipitation variations in south-central New Mexico is examined. Harmonic analysis reveals a strong diurnal cycle in precipitation frequency at all stations studied. In addition, relatively ... -
The Summer Plateau Low Pressure System of Mexico
(American Meteorological Society, 1999-04-01)Average July heights and winds over a 10-yr period are computed at 850 mb over Mexico using both surface and radiosonde data. During the day central Mexico at this level is dominated by low pressure, with some smaller areas ... -
Comments on “Rainfall and Climate Variation over a Sloping New Mexico Plateau during the North American Monsoon”
(American Meteorological Society, 1998-02-01)No abstract is available for this item. -
Surface Mesonets of the Western United States
(American Meteorological Society, 1997-07-01)In recent years the western United States has gone from being a region with relatively sparse surface observations to one that has a number of mesoscale networks maintained by a variety of interests. Expanding population ... -
Salaries and Advancement of Women Faculty in Atmospheric Science: Some Reasons for Concern
(American Meteorological Society, 1996-03-01)Zevin and Seitter's analyses of the 1993 American Meteorological Society membership survey indicated that university/college employees had the largest difference in salary by gender when controlling for experience and age. ... -
The Low-Level Atmospheric Circulation near Tongoy Bay–Point Lengua de Vaca (Chilean Coast, 30°S)
(American Meteorological Society, 2011-11-01)Strong southerly, terrain parallel winds often occur along the coast of north-central Chile (25°–35°S) embedded in the marine atmospheric boundary layer and the lower part of the capping temperature inversion. Their offshore ... -
Aircraft Observations of a Coastally Trapped Wind Reversal off the California Coast
(American Meteorological Society, 2008-02-01)The summertime marine atmospheric boundary layer off the California coast is normally characterized by northerly winds associated with the Pacific high. This pattern is occasionally disturbed by episodes of southerly winds ... -
A Study of the Forcing of the 22–25 June 2006 Coastally Trapped Wind Reversal Based on Numerical Simulations and Aircraft Observations
(American Meteorological Society, 2008-12-01)Coastally trapped wind reversals (CTWRs) occur periodically in the lowest several hundred meters of the marine boundary layer west of California and disrupt the northerly flow that typically occurs during summer. South ... -
Influence of large scale oscillations on upwelling-favorable coastal wind off central Chile
(American Geophysical Union, 2012-10-16)Along the central coast of Chile is typically equatorward, upwelling-favorable wind associated with the southeast Pacific anticyclone. A coastal low-level jet often develops, and its wind speed is mostly controlled by the ... -
Assessing the Influence of the MJO on Strong Precipitation Events in Subtropical, Semi-Arid North-Central Chile (30°S)
(American Meteorological Society, 2012-10-01)Annual precipitation in subtropical, semiarid north-central Chile (30°S) during rainy years comprises a few (3–5) strong events in the fall and winter, which are presumably modulated by the Madden–Julian oscillation (MJO). ...
