We investigated the spatial and temporal distribution of blackfly larvae on a mesohabitat scale atfour different breeding sites in the Brazilian savannah "Cerrado." A total of 2,385 larvae of 12 different species were collected, and three of the sampling sites revealedspecies richness and diversity peaks in April. A principal components analysis was performed to reduce abiotic data into a small...

The Global Precipitation Mission (GPM) Core Observatory that was launched on 27 February 2014 ushered in a new era for estimating precipitation from satellites. Based on their high spatial–temporal resolution and near global coverage, satellite-based precipitation products have been applied in many research fields. The goal of this study was to quantitatively compare two of the latest GPM-era s...

Beta activity of particulate matter in both air and precipitation for 1968 at Los Alamos, New Mexico, is reported. The declining activities for January through April seem to be residual fallout from the 1966 foreign nuclear weapons tests, and the December hi~h seems due to late 1967 tests. The May through September increases reflect the increasing rainfall o:f that period.

Effects of temperature and precipitation on spring dispersal patterns of Frankliniella fusca (Hinds) (Thysanoptera: Thripidae) caught on yellow sticky traps were estimated in central and eastern North Carolina and eastern Virginia, USA, from 1997 to 2001, and in 2004 and 2007. Data were collected from 44 sites within 14 locations over 7 years, resulting in 30 location-year data combinations. Th...

Catchments as space-time filters – a joint spatio-temporal geostatistical analysis of runoff and precipitation J. O. Skøien and G.

Upper-air observations are disproportionately sparse, both temporally and geographically, when compared to surface observations. The lack of data is likely one of the largest limiting factors in numerical weather prediction. Atmospheric measurements performed by the Tropospheric Airborne Meteorological Data Reporting (TAMDAR) sensor of humidity, pressure, temperature, winds aloft, icing, and tu...

This work examines the sources of moisture affecting the semi-arid Brazilian Northeast (NEB) during its pre-rainy and rainy season (JFMAM) through a Lagrangian diagnosis method. The FLEXPART model identifies the humidity contributions to the moisture budget over a region through the continuous computation of changes in the specific humidity along back or forward trajectories up to 10 days perio...

At Colorado State University the Regional Atmospheric Modeling System (RAMS) has been used to produce real-time forecasts of precipitation for the Colorado mountain region since 1991. Originally a so-called dumpbucket scheme was used to generate precipitation, but starting in the fall of 1995 real-time forecasts used the bulk microphysics scheme available with RAMS. For the month of April 1995,...

Changes in precipitation amount and variability have the potential to alter the structure and function of grasslands, but we know little about how changes in the timing of precipitation might aff ect grasslands. Here, we analyze long-term records from a tallgrass prairie to show that shifts in the timing of precipitation during the growing season have little eff ect on primary productivity or g...
