The objectives of the Winter Fog Experiment (WIFEX) over Indo-Gangetic Plains India are to develop better now-casting and forecasting winter fog on various time-and spatial scales.Maximum occurrence northwest is about 48 days (visibility <1000 m) per year, it occurs mostly during December-February time-period.The physical chemical characteristics fog, meteorological factors responsible for its genesis, sustenance, intensity dissipation poorly understood.Improved understanding above aspects...
The radiative effects of black carbon (BC) aerosols over New Delhi, the capital city India, for period August 2010–July 2011, have been investigated using Santa Barbara DISTORT Atmospheric Radiative Transfer (SBDART) model in present paper. monthly mean BC concentrations an urban location, vary between 15.935 ± 2.06 μ g m −3 (December 2010)–2.44 0.58 (July 2011). highest value forcing has found to be November 2010 (66.10 6.86 Wm −2 ) and lowest July 2011 (23 3.89 ). Being host XIX...
The Indian Government implemented the project "System of Air quality Forecasting And Research (SAFAR)" for "Commonwealth Games" 2010 in Delhi. It was adopted by Global Urban Meteorology and Environment World Meteorological Organization as its pilot project. We used data from a dense network stations built over 2500 km2 Delhi under SAFAR to investigate temporal spatial variations fine (PM2.5) coarse (PM10–2.5) particles, discuss their deposition airborne mass fractions that were retained...
We investigate the special behavior in distribution of boundary layer ozone and its precursors over world's most extensive tract uninterrupted alluvium intensively farmed zones situated foothills Himalayas as major river basin, known Indo‐Gangetic Plains (IGP). The study makes use a Chemistry‐Transport Model forced with dynamical fields new emission inventories pollutants established for 2001. It is found that IGP region highly vulnerable to human induced pollutant emissions due conducive...
Rainwater samples collected at Sinhagad on 65 rain occasions during monsoon season (June–September 2005) and 23 post-monsoon (October-November with standard collection instruments, i.e. wet-only (WO) bulk collectors (BC), were considered for the present study. is a hill station mountaintop in Western Ghats, located about 40 km southwest of Pune. The following ionic components determined: H+, NH4+, Ca2+, Mg2+, K+, Na+, SO42-, NO32-, Cl- F-. pH analyses showed that rainwater both seasons...
Abstract This paper presents a study of spatiotemporal variation lightning activity over Peninsular India (8°–22°N, 72°–88°E) by using monthly satellite-based flash grid (1° × 1°) data for period 10 yr (1998–2007). The are examined in terms spatial, annual, and seasonal distribution the activity. It is found that higher south eastern India. On time scale, shows two maxima—first month May then September. monsoon noticed to be considerable because occurrence low-level jet increase break...
