Zamra catchment, Upper Tekeze Basin, Northern Ethiopia. Direct field estimates of potential evapotranspiration (PET) remain a challenge, because they are expensive and have limited spatial representativeness. An alternative is to derive PET by remote sensing as product reference (ETo) land use-land cover (LULC) factor (Kc). The aims this study were to: i) validate satellite-derived Daily Refere...

[1] The Leeuwin Current, a warm, poleward flowing eastern boundary current, dominates the surface circulation off the west coast of Australia and has profound influence on regional marine ecosystem and fisheries recruitment. In this study, the seasonal and interannual variations of upper ocean heat balance in the Leeuwin Current region are analyzed by using an eddy-resolving numerical model sim...

Abstract Snow’s thermal and radiative properties strongly impact the land surface energy balance thus atmosphere above it. Land snow information is poorly known in mountainous regions. Few studies have examined of initial conditions high-resolution, convection-permitting numerical weather prediction models during midlatitude cool season. The extent to which influences atmospheric transport subs...

In recent decades, renewable energy projects have required careful consideration of environmental factors. This study investigates the impact a mid-latitude cyclone on planned floating photovoltaic (FPV) facilities in Antalya, Turkey, focusing severe thunderstorm events that brought heavy rainfall and tornadoes January 2019. Synoptic analysis reveals deep cut-off low over Genoa Gulf, causing tr...

Bag silos made at three research farms in 2000 and 2001 were monitored at filling and emptying to determine densities and losses. A total of 47 bags (23 alfalfa, 1 red clover, 23 whole−plant corn) were made, and losses were calculated on 39 of the silos. Dry matter (DM) density ranged from 160 to 270 kg/m3. Dry matter density increased with DM content in hay crop silages on average 2.9 kg/m3−% ...

To investigate the prevalence of Cryptosporidium infection in horses, a total of 200 fecal specimens were collected randomly from five farms in Tehran. Samples were taken during a year, 50 specimens each season. Of these specimens, 57 were obtained from Caspian Pony. The presence of oocysts in the samples was confirmed by modified Ziehl-Neelsen staining of direct smears of the fecal material fr...

one of the most important atmospheric systems in the eurasian continent during the northern hemisphere winter season is the siberian high pressure. in this study, using the ncep/ncar reanalysis data for winters of 1948-2008, trend of changes in the intensity of the high system center and its effects on some meteorological fields are investigated. the results show that the 2m height mean tempera...

The weather succeeding the cyclone was very fine and warm, but about the 10th of tho month a change occurred : the sky becamo overcast, and the air moist. Occasional showers of rain fell, and the atmosphere was damp and raw. This continued up to the 15th, and was followed to tho end of tho month by sustained fine weather. Fevers have been very prevalent during this month, and cholera began to a...

The shallow atmospheric fronts that develop in the early winter along the east coast of North America have been attributed, in various modeling and observational studies, to the land–sea contrasts in both surface heating and friction. However, typical synoptic conditions are such that these ‘‘coastal’’ fronts could also be a type of upstream influence by the Appalachian Mountain chain. Generali...
