This study analyzes the air–water flow properties in overflow nappe jets. Data were measured several cross-sections of rectangular free-falling jets downstream a sharp-crested weir, with maximum fall distance 2.0 m. The obtained using conductivity phase-detection probe. Furthermore, back-flushing Pitot-Prandtl probe was used order to obtain velocity profiles. Five specific flows rates analyzed,...
When searching for food, foraging fishes expose themselves to hidden predators. The strategies that maximize the survival of foraging fishes are not well understood. Here, we describe a novel type of mobbing behaviour displayed by foraging Scolopsis affinis. The fish direct sharp water jets towards the hidden sessile annelid predator Eunice aphroditois (Bobbit worm). We recognized two different...
[1] An analysis of thunderstorm environment, structure, and evolution associated with six gigantic jets (five negative polarity, one positive) was conducted. Three of these gigantic jets were observed within detection range of very high frequency lightning mapping networks. All six were within range of operational radars and two-dimensional lightning network coverage: five within the National L...
