RISTrends in U.S. Total Cloud Cover from a Homogeneity-Adjusted Dataset
Publisher: American Meteorological Society
Abstract: loud cover data from ground-based weather observers can be an important source of climate information, but the record of such observations in the United States is disrupted by the introduction of automated observing systems ...
Time-Varying Biases in U.S. Total Cloud Cover Data
Publisher: American Meteorological Society
Abstract: his paper presents evidence of significant discontinuities in U.S. cloud cover data from the Integrated Surface Database (ISD) and its predecessor datasets. While long-term U.S. cloud records have some well-known homogeneity ...
Variations in Low Cloud Cover over the United States during the Second Half of the Twentieth Century
Publisher: American Meteorological Society
Abstract: Several changes in U.S. observational practice [in particular, the introduction of the Automated Surface Observing System (ASOS) in the early 1990s] have led to a challenging heterogeneity of time series of most ground-based ...
Comparisons of Surface Meteorology and Turbulent Heat Fluxes over the Atlantic: NWP Model Analyses versus Moored Buoy Observations
Publisher: American Meteorological Society
Abstract: Surface meteorological variables and turbulent heat fluxes in the National Centers for Environmental Prediction?National Center for Atmospheric Research reanalyses 1 and 2 (NCEP1 and NCEP2) and the analysis from the ...
Mean and Variability of the WHOI Daily Latent and Sensible Heat Fluxes at In Situ Flux Measurement Sites in the Atlantic Ocean
Publisher: American Meteorological Society
Abstract: Daily latent and sensible heat fluxes for the Atlantic Ocean from 1988 to 1999 with 1° ? 1° resolution have been recently developed at Woods Hole Oceanographic Institution (WHOI) by using a variational object analysis ...
Improving Latent and Sensible Heat Flux Estimates for the Atlantic Ocean (1988–99) by a Synthesis Approach
Publisher: American Meteorological Society
Abstract: A new daily latent and sensible flux product developed at the Woods Hole Oceanographic Institution (WHOI) with 1° ? 1° resolution for the Atlantic Ocean (65°S?65°N) for the period from 1988 to 1999 was presented. The flux ...
Comparison between Total Cloud Cover in Four Reanalysis Products and Cloud Measured by Visual Observations at U.S. Weather Stations
Publisher: American Meteorological Society
Abstract: homogeneity-adjusted dataset of total cloud cover from weather stations in the contiguous United States is compared with cloud cover in four state-of-the-art global reanalysis products: the Climate Forecast System Reanalysis ...
Recent Trends in Cloudiness over the United States: A Tale of Monitoring Inadequacies
Publisher: American Meteorological Society
Abstract: Automated Surface Observation Systems (ASOS) were widely introduced to replace manned weather stations around the mid-1990s over North America and other parts of the world. While laser beam ceilometers of the ASOS in North ...
Recent Changes in Cloud-Type Frequency and Inferred Increases in Convection over the United States and the Former USSR
Publisher: American Meteorological Society
Abstract: Significant changes and a general redistribution in the frequencies of various cloud types have been observed during the past 40?50 years over the midlatitude land areas of the Northern Hemisphere. This is evident for North ...
The Relationship of Cloud Cover to Near-Surface Temperature and Humidity: Comparison of GCM Simulations with Empirical Data
Publisher: American Meteorological Society
Abstract: One of the possible ways to check the adequacy of the physical description of meteorological elements in global climate models (GCMs) is to compare the statistical structure of these elements reproduced by models with ...
