This paper presents an evaluation and validation of the Naval Research Laboratory's COAMPS real-time forecasts during the VOCALS-REx over the area off the west coast of Chile/Peru in the Southeast Pacific during October and November 2008. The analyses focus on the marine boundary layer (MBL) structure. These forecasts are compared with lower troposphere soundings, in situ surface measurements,and satellite observations. The predicted mean MBL cloud and surface wind spatial distributions ...
The Sun Earth Connection Coronal and Heliospheric Investigation (SECCHI) coronagraphs on the twin Solar TErrestrial RElations Observatory (STEREO) spacecraft provide simultaneous views of the corona and coronal mass ejections from two view points. Here, we analyze simultaneous image pairs using the technique of tie-pointing and triangulation (T&T) to determine the three-dimensional trajectory of seven coronal mass ejections (CMEs). The bright leading edge of a CME seen in coronagraph images results ...
This is a systematic account of the use of dimensional analysis in constructing similar conditions for models and structures. Analysis covers large deflections, buckling, plastic behavior, and materials with nonlinear stress-strain characteristics as well as simpler structural problems. To test validity of similarity principles for structures involving buckling and plastic flow, measurement of strains and displacements were made on square thin sheets in shear with and without holes. With certain ...
