During hurricane seasons, emergency managers and other decision makers need accurate and ‘on-time’ information on potential storm surge impacts. Fully dynamical computer models, such as the ADCIRC tide, storm surge, and wind-wave model take several hours to complete a forecast when configured at high spatial resolution. Additionally, statically meaningful ensembles of high-resolution models (ne...

The magnitude of the Disturbance Storm Time (Dst) index varied in relation to extremely small negative integer that indicated a large geomagnetic storm. sharpened variants Dst indices could describe detailed features was estimated using an algorithm through time and frequency-domain band-stop filtering remove solar-quiet variation mutual coupling effects between Earth’s rotation, Moon’s orbit, ...

Method: For this purpose, foF2 data from four Antarctic stations were analyzed during three intense magnetic storms occurred in high solar activity (years 2002 and 2003). In general, negative storm effects irrespective of the local time were observed during the first part of the storms (main phase). Negative effects were also observed more often than positive effects during the first part of th...

In August 2013, we observed a high incidence (44%) of synchronous bands of reduced melanin (a type of fault bar we have termed "pallid bands") across the rectrices of juvenile Grasshopper Sparrows (Ammodrammus savannarum) captured near El Reno, Oklahoma. Earlier that year, on May 31, the site was struck by a severe storm which rained hailstones exceeding 5.5 cm diameter and spawned an historic ...

a knowledge of rainfall distribution over a finite area is needed for small bydraulic structures design. hydrologists have always been concerned about depth- area- duration (dad) for a specific storm in a watershed. an intense storm occurred on june 6, 1992 which claimed some lives in parts of mashhad, khorasan province, iran. data of rainfall depth at 29 raingauge stations around the city and ...

introduction one of the factors that affect the climate of arid and semi-arid areas is dust storm. numerical models are new methods for evaluation of dust storms which can also be used for forecasting dust storms. weather patterns that lead to dust outbreaks can be simulated using computer models that support a wide range of simulations related to the long-range transport, dispersion, and depos...

dust storm is a meteorological phenomenon common in arid and semi-arid regions. iran and particularly its west and south-west parts, periodically faces with the dust phenomenon and its problems. in this investigation two dust samples has been selected and studied that they has sustained over three days with visibility less than 1000m in west of iran. the first one occurred during 18 - 21 april ...
