Clouds forming during the summer monsoon over the Indian subcontinent affect its evolution through their radiative impact as well as the release of latent heat. While the latter is previously studied to some extent, comparatively little is known about the radiative impact of different cloud types and the vertical structure of their radiative heating/cooling effects. Therefore, the main aim of t...

A large number of intermediate basic volcanic rocks and porphyry Cu-Mo deposits as well volcanic-hosted magnetite deposit have been recently discovered in the Xilekuduk area. However, no reports concerning petrogenesis age or their relationship with mineralization published to date. The purpose this study was make up for absence previous studies on Devonian activities area confirm between two s...

The boreal summer intraseasonal oscillation (ISO) in the global tropics is documented here using a 7-year suite (1998–2004) of satellite measurements. A composite scenario was made of 28 selected events with reference to the oscillation in the eastern equatorial Indian Ocean (EIO), where the oscillation is most regular and its intensity is indicative of the strength of the subsequent northward ...

Recent observational analysis reveals the central role of three multi-cloud types, congestus, stratiform, and deep convective cumulus clouds, in the dynamics of large scale convectively coupled Kelvin waves, westward propagating two-day waves, and the Madden–Julian oscillation. The authors have recently developed a systematic model convective parametrization highlighting the dynamic role of the...

A train of Kelvin–Helmholtz billows in a deep stratiform cloud over a mountain range is documented using data from a high-resolution vertically pointing airborne Doppler radar. The billows had a spacing of 2–2.5 km and a small aspect ratio. The formation and decay of the billows appear to be related to flow acceleration over a mountain.

Copper and associated gold mineralization in the Mundiyawas-Khera area of western India is hosted by Proterozoic felsic volcanic rocks rhyo-dacite composition. Signatures hydrothermal alteration represented sericite, epidote, scapolite carbonates are well observed around ore zone. The with gently to flat sloping REE pattern, variable negative Eu anomaly, intermediate abundances HFSE moderate lo...
