[1] We study ring current evolution during the 10 January 1997 geomagnetic storm, comparing results from two inner magnetospheric convection electric field models: (1) the Kp-dependent Volland-Stern (V-S) model and (2) the high spatial and temporal resolution assimilative mapping of ionospheric electrodynamics (AMIE) model, coupled with our global ring current model. We have added a penetration...

background and objectives: hyperthyroidism can occur with pregnancy. thyroid storm is a life-threatening exacerbation of hyperthyroidism. the mortality rate for thyroid storm remains surprisingly high at approximately 20%. case report: a 21-year-old primigravida woman presented at 25 weeks, with severe pre-eclampsia and uncontrolled hyperthyroidism was scheduled for emergency cesarean section. ...

A large proportion of nutrients and sediment is mobilised in catchments during storm events. Therefore understanding a catchment's hydrological behaviour during storms and how this acts to mobilise and transport nutrients and sediment to nearby watercourses is extremely important for effective catchment management. The expansion of available in-situ sensors is allowing a wider range of water qu...

The steady-state assumption commonly used in object-based tracking algorithms may be insufficient to determine the right track when a convective storm goes through complicated evolution. Such an issue is exacerbated by relatively coarse output frequency of current convection allowing model (CAM) forecasts (e.g., hourly), giving rise many spatially well resolved but temporally not storms that co...

Agricultural drought, a common phenomenon in most parts of the world, is one of the most challenging natural hazards to monitor effectively. Land surface water index (LSWI), calculated as a normalized ratio between near infrared (NIR) and short-wave infrared (SWIR), is sensitive to vegetation and soil water content. This study examined the potential of a LSWI-based, drought-monitoring algorithm...

Abstract We demonstrate the utility of transient polarimetric signatures ( Z DR and K DP columns, a proxy for surges in thunderstorm updraft) to explain variability lightning flash rates tornadic supercell. Observational data from WSR-88D Oklahoma mapping array are used map temporal variance VHF sources channels. It is shown, via three-dimensional cross-sectional analyses, that storm was invert...
