%X Based onthe characteristics,mechanisms and impacts of the dry intrusion,a dry intrusion index(DII) is defined to characterize the dry intrusionintensity and its physical interpretation is explored by a case study as well.It is found that DIIis related to the horizontal temperature advection,the potential vorticity and pseudo-equivalent potential temperature.The positive DII indicates that there exists the dry intrusionprocess.And the greater the positive DIIis,the stronger the dry intrusion exists.Thus,this...
