Conditions Associated With Cold Season Dense Fog in the Midwestern United States
The physical dimensions and onset time of dense fog appeared to be the best predictors of fog duration for all types of fog. Longer lasting events tended to form earlier in the night, to be more opaque and widespread, and to dissipate several hours later than short-lived events. The longer …

Structure and statistical analysis of the microphysical properties of the comma-head region of cold-season midlatitude cyclones
… precipitation in the comma-head region of cold-season continental cyclones, using data collected by the W-band Wyoming Cloud Radar and in-situ instrumentation aboard the NSF/NCAR C-130 research aircraft during the 2009-10 Profiling of Winter Storms (PLOWS) field campaign. The analyses …

Spatial and Seasonal Variations in Aridification Across Southwest North America
… US), depending on the relative contributions of cold and warm season P and E. Interpreting the spatial and seasonal variations of the projected aridification is important for understanding the potential impacts of climate change on SWNA regional hydrology. We compare the projected trends in P, E, …

Hailfall in a future climate using a pseudo-global warming approach
… increases in hydrometeor loading. However, only cold-season events showed an increase in hail sizes both within the storm and at the surface, whereas warm-season events saw a decrease in hail sizes at the surface and aloft. Changes in the hailfall area at the ground also showed a seasonal trend, …

Shoreline recession: past, present, and future, Lake Sakakawea, North Dakota
… due to wave erosion. Erosion over the cold months occurs as a result of thaw failure. </p><p>The most important variables associated with shoreline recession include: bank height, effective fetch, offshore slope angle, beach width, mean grain size, percentage of coarse beach clasts, …

Design Tool for a Ground-Coupled Ventilation System
… temperatures are relatively higher during the cold season and lower during the hot season, the system takes advantage of this natural phenomenon. This research focused on designing a ground-coupled ventilation system evaluation tool of many factors that affect system performance. The tool …

Spatial and temporal patterns of visibility in Las Vegas, July 2000--July 2001
… a well-defined diurnal pattern during the cold season, and showed the influences of local activities (such as road construction) during the study. Overall, the urban site had the highest levels of visibility impairment, but during midday the visibility at this site improved and was …

Formation and Development of Diabatic Rossby Vortices in a 10-Year Climatology
… northeast. While more DRVs form during the warm season, a larger fraction of storms that explosively deepen occur during the cold season. Composite analyses bear strong resemblance to DRV structural plots in the published literature, confirming that moisture, baroclinicity and the diabatic …

Comparison Of Ceres-Modis Derived Polar Cloud Properties With Cloudsat/calipso And Ground-Based Measurements
… warm months (May-October), retrievals during the cold season (November-April) significantly underestimate CF. Annual mean cloud-base heights derived from ARM and CC agree within 200 m, while their cloud-top heights (Htop) differ by an average of 1.2 km, due largely to CC detecting more upper-level …

Integrated Study Of Dinoflagellate Diversity In The Gulf of Naples
… of marine planktonic communities. To study their seasonal diversity at the LTER-MC station in the Gulf of Naples, I used high throughput sequencing (HTS) metabarcoding of the V4 region in the 18S rDNA. To taxonomically identify the metabarcode sequences, I established a database, called DinoREF, …

Assessment of Model Forecast Temperature Bias During Cold Air Damming in the Central Appalachian Mountains
Cold-air damming (CAD) is a prevalent Mid-Atlantic United States weather phenomenon that occurs when cold, dense air is dammed alongside the eastern slopes of the Appalachian Mountains. Lower-than-normal maximum temperatures, increased and prolonged cloud cover, and precipitation that produces …

Cool Temperature Effects on Productivity and Photosynthesis of Two Biomass Fuel Species: Switchgrass (Panicum virgatum) and Miscanthus (Miscanthus x giganteus)
… "mol m-2s-1). Miscanthus has demonstrated cold tolerance in previous studies, and here showed no significant decrease in the productivity or photosynthetic rates in cool, compared with warm, growing conditions (Amax=8.2 "mol m-2s-1 and 7.0 "mol m-2s-1 for warm and cool conditions, …

A PARTICIPATORY APPROACH TO ASSESS CHILDREN PERSONAL EXPOSURE TO BLACK CARBON IN AN URBAN ENVIRONMENT: SPATIAL ANALYSIS, PERSONAL MEASUREMENTS, AND POSSIBLE MITIGATION ACTIONS.
… part, BC was monitored on fixed sites during two seasons in a school catchment area. The monitoring sites were identified by involving the school, schoolchildren parents and the residents of the neighborhood. The spatial distribution of the contaminant was studied and modelled as well, focusing in …

A Reconstruction of Post-Glacial Hydroclimatic Change and Mass Accumulation Rates from a Small Watershed of the Lower North American Great Lakes Region
… were caused by some combination of reduced warm-season precipitation, reduced cold-season precipitation, and increased evaporation. Changes in seasonal moisture amounts were driven by variations in the shape and latitude of the Polar jet stream, which dictated atmospheric circulation patterns. …

Effect of NPK basal fertilizer, nitrogen top dressing and season on growth and yield of Cucurbita argyrosperma
… NPK basal fertilizer, nitrogen top dressing and seasonal variation on the agronomic traits of C. argyrosperma. Plants were grown at 0; 150; 300 and 450 kg ha-1 NPK basal fertilizer and 0; 150 and 300 kg ha-1 nitrogen top dressing during warm and cold seasons. The application of 300 kg ha-1 NPK …

Ecto-and endo- parasites of silver kob (Argyrosomus Inodorus) from northern Namibia (21º 24ºS)
… intensity and mean abundance were analysed by season of capture, fish length and fish sex. Chi-square tests were used to determine differences in mean abundance by season, host sex and host length. Twenty-eight species from 17 parasite genera were found, including monogeneans (five Diplectanum …
