TRANSPORT OF SULFUR OXIDES lHTHIN THE LOS ANGELES SEA BREEZE/LAND BREEZE CIRCULATION SYSTEM

نویسنده

  • Glen R. Cass
چکیده

The sea breeze/land breeze circulation system in the Los Angeles a r ea results in transport of pollutants seaward at nigh t followed by return of aged material inland the next day . This characteristic wind reversal pattern both increases the r etention time available for the oxidation of S02 to form sulfates and causes individual a ir parcels to make mul tiple passes over large coas tal emissions sources. As a result, the Los Angeles atmosphere exhibits high peak day and high annua l mean s ulfate concentrations in spite of the fa c t that s ulfate conce ntrations in marine background o r desert air are low.

Transport of Sulfur Oxides within the Los Angeles Sea Breeze/land Breeze Circulation System

The sea breeze/land breeze circulation system in the Los Angeles area results in transport of pollutants seaward at night followed by return of aged material inland the next day. This characteristic wind reversal pattern both increases the retention time available for the oxidation of S02 to for m sulfates and causes individual air parcels to make multiple passes over large coastal emissions so...

Variability of three-dimensional sea breeze structure in southern France: observations and evaluation of empirical scaling laws

Sea-breeze dynamics in southern France is investigated using an airborne Doppler lidar, a meteorological surface station network and radiosoundings, in the framework of the ESCOMPTE experiment conducted during summer 2001 in order to evaluate the role of thermal circulations on pollutant transport and ventilation. The airborne Doppler lidar WIND contributed to three-dimensional (3-D) mapping of...

Transport and dispersion of atmospheric sulphur dioxide from an industrial coastal area during a sea-breeze event

Experimental and modelling results of the dynamics of a sea-breeze event and its effects on the three-dimensional (3-D) redistribution of the gaseous SO 2 are presented within the framework of a particularly flat and industrialized coastal area of the North Sea. The measurements were carried out at ground level with the stations of the local 5 air quality monitoring agency and with two optical ...

Comparisons between Mesoscale Model Terrain Sensitivity Studies and Doppler Lidar Measurements of the Sea Breeze at Monterey Bay

A NOAA/Environmental Technology Laboratory Doppler lidar measured the life cycle of the landand seabreeze system at Monterey Bay, California, in 1987, during the Land–Sea Breeze Experiment (LASBEX). On days with offshore synoptic flow, the transition to onshore flow (the sea breeze) was a distinct process easily detected by lidar. Finescale lidar measurements showed the reversal from offshore t...
