Multi-wavelength signatures of magnetic reconnection of a flare associated coronal mass ejection
Bhuwan Joshi, P. K. Manoharan, Astrid M. Veronig +2
The evolution of an X2.7 solar flare, that occurred in a complex magnetic configuration region on 2003 November 3 is discussed utilizing a multi-wavelength data set. The v…
North-South Asymmetry of Solar Activity during Cycle 23
Bhuwan Joshi, P. Pant, P. K. Manoharan +1
In this paper, we have made a statistical analysis of solar H flares that occurred during the period 1996 to 2005 to investigate their spatial distribution with respect to nort…
Characteristics of Aerosol Spectral Optical Depths over Manora Peak, Nainital A High Altitude Station in the Central Himalayas
Ram Sagar, Brijesh Kumar, U. C. Dumka +2
We present, for the first time, spectral behaviour of aerosol optical depths (AODs) over Manora Peak, Nainital located at an altitude of 2 km in the Shivalik ranges of centr…
North-South Distribution of Solar Flares during Cycle 23
Bhuwan Joshi, P. Pant, P. K. Manoharan
In this paper, we investigate the spatial distribution of solar flares in the northern and southern hemisphere of the Sun that occurred during the period 1996 to 2003. This period…
Periodicities in sunspot activity during solar cycle 23
Bhuwan Joshi, P. Pant, P. K. Manoharan
The data of sunspot numbers, sunspot areas and solar flare index during cycle 23 are analyzed to investigate the intermediate-term periodicities. Power spectral analysis has been p…
Aerosol Characteristics at a high-altitude station Nainital during the ISRO-GBP Land Campaign-II
Auromeet Saha, P. Pant, U. C. Dumka +3
During the second land campaign (LC-II) organised by ISRO-GBP, extensive ground-based measurements of aerosol characteristics were carried out over Manora Peak (29.4oN; 79.5oE; 195…
Aerosol contents at an altitude of ~2 km in central Himalayas
Ram Sagar, B. Kumar, P. Pant +3
Aerosols, both natural and anthropogenic, play an important role in the atmospheric science, by imparting radiative forcing and perturbing the radiative balance of the Earth atmosp…
The Chiral Potts Model and Its Associated Link Invariant
F. Y. Wu, P. Pant, C. King
A new link invariant is derived using the exactly solvable chiral Potts model and a generalized Gaussian summation identity. Starting from a general formulation of link invariants…
Aerosol Characteristics at a High Altitude Location in Central Himalayas: Optical Properties and Radiative Forcing
P. Pant, P. Hegde, U. C. Dumka +3
Collocated measurements of the mass concentrations of aerosol black carbon (BC) and composite aerosols near the surface were carried out along with spectral aerosol optical depths…
