Abstract

IN A NUMERICAL STUDY, A MODEL IS USED TO INVESTIGATE THE IMPACT OF THE ADDITION OF SEA-SALT AEROSOL PARTICLES ON THE EVOLUTION OF MARINE STRATOCUMULUS CLOUD. THE MODEL USED CALCULATES THE MICROPHYSICAL AND CHEMICAL DEVELOPMENT OF AN INPUT AEROSOL SPECTRUM (AT 99% RH) AS THE AIR PARCEL IN WHICH THEY RESIDE IS SUBJECTED TO ADIABATIC COOLING AS IT IS FORCED TO RISE UP THROUGH THE LAYER BETWEEN CLOUD BASE AND CLOUD TOP. THE VARIATIONS OF MICROPHYSICAL PARAMETERS WITH HEIGHT ABOVE CLOUD BASE HAVE BEEN EXAMINED FOR SEVERAL DIFFERENT UPDRAUGHT VELOCITIES, CLOUD BASE TEMPERATURES AND INPUT DRY AEROSOL NUMBER AND SIZE DISTRIBUTION. THE RESULTS SHOW THAT THE MICROPHYSICAL STRUCTURE OF LAYER CLOUDS WAS STRONGLY AFFECTED BY THE PHYSICAL PROPERTIES OF THE AEROSOL PARTICLES FROM WHICH THE CLOUD DROPLETS GREW. FURTHER MODEL RUNS WITH ELEVATED SEA SALT AEROSOL CONCENTRATIONS SHOWED THE CLOUD ALBEDO EFFECTS RELATED TO THESE PERTURBATIONS IN BACKGROUND MARINE AEROSOL MAY CONSTITUTE A NEGATIVE FEEDBACK TO GLOBAL WARMING. AN IMPLICATION IS THAT THE INTRODUCTION OF SEA-SALT AEROSOL INTO CLOUD, PERHAPS BY MECHANICALLY PRODUCING SEA-SALT AT THE SURFACE, MAY BE A METHOD FOR OFFSETTING GLOBAL WARMING. IN THIS STUDY THE MODELLED MICROPHYSICAL PROPERTIES OF STRATOCUMULUS CLOUD HAVE BEEN EXAMINED. DATA OBTAINED FROM A DIFFERENTIAL MOBILITY PARTICLE SIZER (DMPS) AND AN ACTIVE SCATTERING AEROSOL SPECTROMETER PROBE-MODEL X (ASASP-X) IN THE FORM OF A TYPICAL MARITIME AEROSOL SIZE DISTRIBUTION FROM THE ACE-2 EXPERIMENT HAVE BEEN USED AS INPUT TO A MODEL.
