ATMOSPHERIC STIRRING MEASURED BY PRECIPITATION

Relating global precipitation to atmospheric fronts

[1] Atmospheric fronts are important for the day-to-day variability of weather in the midlatitudes, particularly during winter when extratropical storm-tracks are at their maximum intensity. Fronts are often associated with heavy rain, and strongly affect the local space-time distribution of rainfall. A recently developed objective front identification method that distinguishes between cold, wa...

Ocean Stirring by Swimming Bodies

Transport and stirring induced by vortex formation

The purpose of this study is to analyse the transport and stirring of fluid that occurs owing to the formation and growth of a laminar vortex ring. Experimental data was collected upstream and downstream of the exit plane of a piston–cylinder apparatus by particle-image velocimetry. This data was used to compute Lagrangian coherent structures to demonstrate how fluid is advected during the tran...

Normal Renal Dimensions in Iranian Adults Measured by Ultrasound

Introduction: Correct interpretation of kidney images requires the knowledge of its normal size. This study aimed to establish normal values for kidney length and parenchymal thickness and identify the potential related factors in a group of Iranian adults. Methods: Renal dimensions, including length and parenchymal thickness were measured by sonography in 103 individuals with n...

Spatial relationship between the atmospheric circulation and the precipitation measured in the western Swiss Alps by means of the analogue method

An adaptation technique based on the synoptic atmospheric circulation to forecast local precipitation, namely the analogue method, has been implemented for the western Swiss Alps. During the calibration procedure, relevance maps were established for the geopotential height data. These maps highlight the locations were the synoptic circulation was found of interest for the precipitation forecast...
