Faraz Khan of GCCN, Pakistan said that leading Pakistani and foreign companies have brought their alternative energy products and technology for demonstration to the potential users, such conferences, are essential to promote the green natural resources.
Urban environments, with abundant pollutant CCN and GCCN, thus also modify cloud microphysical processes (after dynamical effects initiate it, as discussed above).
Droplets that form on GCCN such as sea salt can accelerate autoconversion, while droplets that form on the smaller CCN reduce autoconversion rates and result in suppressed precipitation, enhanced cloud mass fluxes, a colder and drier boundary layer, larger surface fluxes, a warmer and more humid atmosphere, and a lower convective available potential energy .
Increased CCN concentration may reduce autoconversion rates since smaller particles do not coalesce as efficiently as do the larger GCCN and must compete for the available liquid water content.
They found that increasing GCCN concentration enhanced total accumulated precipitation while simultaneously increasing both CCN and GCCN concentrations suppressed rainfall.
Simulations with zero PSD updates were assigned constant CCN and GCCN concentrations of 300 [cm.sup.-3] and 20 [cm.sup.-3], respectively, as these values represent modal data averages for the month of July 2007 Simulations with ingested observed PSD updates were modified as data was available, amounting to 11 updates during July 2007.
Precipitation enhancement (denoted by negative values) due to the presence of bigger and more numerous GCCN particles over most of the region, including the northwestern storm (41N/74.6W), occurs with the introduction of HVCM PSD.
These results show that increased CCN delays the occurrence of the intense precipitation, while GCCN causes the cloud to rain out early, allowing for newly activated CCN to rise higher in Run 2 before they grow enough to overcome cloud updrafts.
Bigg and colleagues (2015) suspected that for the cloud-active aerosols that are usually present only at low concentrations in the atmosphere (GCCN and certain INPs), increases in their abundance due to rainfall could have notable effects on subsequent rainfall leading to feedback.
