In wet season, the circulation of local wind at Bandung basin have semidiurnal pattern and there is the influence of convective activity. But in previous research have some lack. Then in this research, was done the same thing with previous research yet by adding some instrumenst and poinst observation that be used. <br /> <br /> <br /> <br /> <br /> This research use the AWS (Automatic Weather Station) that be laid at seven points from north to south of Bandung basin in wet season. The observation was <br /> <br /> <br /> <br /> <br /> done from 11th December 2014 until 30th January 2015. <br /> <br /> <br /> <br /> <br /> The result of research explain pattern of anabatic wind at Bandung basin in wet season is divided become three of categories. The three of categories are pattern <br /> <br /> <br /> <br /> <br /> at weak convection (wc), strong convection (sc), and strong convection with rain event (scr). On weak convection condition, after 12.00 WIT anabatic wind tend to move to Lembang after it moved to Lembang and Banjaran. This thing is caused by north part of Bandung basin get more heat budget from solar radiation so that <br /> <br /> <br /> <br /> <br /> the pressure gradient is bigger at north part. Then on strong convection and strong convection with rain event condition after 12.00 WIT the wind still move to Lembang and Banjaran however after 15.00 WIT the wind on strong convection with rain event change the direction to Lembang. Then on weak convection, the pattern of anabatic wind is not influenced by convective activity whereas on strong convection and strong convection with rain event condition, the pattern of anabatic wind is influenced by convective activity.
