Theory suggests that natural fire regimes can result in landscapes that are both self-regulating and resilient to fire. For example, because fires consume fuel, they may create barriers to the spread of future fires, thereby regulating fire size. Top-down controls such as weather, however, can weaken this effect. While empirical examples demonstrating this pattern-process feedback between veget...

Normally wind measurements from Doppler radars rely on the presence of rain. During fine weather, insects become a potential radar target for wind measurement. However, it is difficult to separate ground clutter and insect echoes when spectral or polarimetric methods are not available. Archived reflectivity and velocity data from repeated 5 scans provide alternative methods. The probability of ...

Hurricane Sandy in late October 2012 drove before it a storm surge that rose to 4.28 meters above mean lower low water at The Battery in lower Manhattan, and flooded the Hugh L. Carey automobile tunnel between Brooklyn and The Battery. This study examines the surge event in New York Harbor using the Weather Research and Forecasting (WRF) atmospheric model and the Coupled-Ocean-Atmosphere-Wave- ...

Interactive display systems give users flexibility to tailor visual displays to different tasks and situations. But this flexibility can only be beneficial if users have metaknowledge of the types of displays that are effective for different purposes. In previous studies with both Navy forecasters and undergraduate students, we found that users often prefer maps that display extraneous variable...

Introduction: In spite of public health level improvement in Iran, Malaria is still an important health problem in the southeast corner of the country. Mapping distribution of endemic diseases with their relations to geographical factors has become important for public health experts. This study was carried out to provide the distribution maps of the geographical pathology of Malaria in Iran wi...
