A seedable (S) cloud is one that has a large concentration of supercooled water above the  freezing level. using titan the meteorologist can cut a cross-section through the cloud to view the vertical extent of the cloud water. usually, clouds with a high convective energy (CAPE) and a low cap are seedable. A cap, which is a warm layer above the ground, reduces the buoyancy of the cloud water and acts as a lid precluding any further development. the vertically integrated liquid (vil) of the cloud is also monitored. vil is the amount of cloud mass per unit area. seedable clouds have high vil.
