Combined Clear-air Radar And Sodar Observations Of Mesoscale And Microscale Structures Ina Cold Front

Autor: F.M. Ralph, M. Crochet, S.V. Venkateswaran, C. Mazaudier

Publikováno v: [Proceedings] IGARSS'91 Remote Sensing: Global Monitoring for Earth Management.

This study combines observations from remote sensing instruments and a surface mesonetwork to examine important mesoscale and microscale features associated with a cold front. Sodar observations of the front reveal its similarity to a gust front and

The dark spots on the solar disk, some of them are visible with the naked eye, and the aurorae, especially those strectching down to the tropics, are the best visible manifestations of the solar activity. Since more than one century, we know that thi

Global disturbance of the transient magnetic field associated with thermospheric storm winds on March 23, 1979

Autor: Michel Menvielle, Ousseini Fambitakoye, C. Mazaudier

Publikováno v: Journal of Geophysical Research. 95:15209

During large magnetic storms, wind disturbances produces by auroral phenomena can affect the whole thermospheric circulation and associated ionospheric dynamo currents for many hours after the end of the storm. This paper presents a morphological ana

Nocturnal thermal disequilibrium of theF2region ionosphere at middle latitudes

Autor: Pierre Bauer, C. Mazaudier

Publikováno v: Journal of Geophysical Research. 81:3447-3451

Incoherent scatter measurements performed above St. Santin (44degree3'N,2degreeE) in the F/sub 2/ region over the period 1971--1972 have revealed the existence of a small systematic temperature difference (10--20 K) between the electrons and the ions
