1. Moving westward, it occasionally produced bursts of convective activity , before dissipating on August 18. 2. Tropical cyclones form as a result of significant convective activity , and are warm core. 3. The NHC noted that a convective activity and Christine weakened to a tropical depression. 4. "' Stratocumulus Castellanus "'have stronger convective activity due to the presence of increasingly unstable air. 5. By the late morning hours, little convective activity remained around the low pressure center of Felicia. 6. The first convective activity across the basin and prevented the formation of strong low pressure areas. 7. Following a brief increase in convective activity , the storm slightly intensified before succumbing to wind shear once more. 8. On October 24 the low-level center had completely dissolved, and only a small area of convective activity persisted. 9. One of the cyclones, Cyclone Erica, originated from the convective activity and thus cyclone development in the basin. 10. Change in the African easterly jet and AEWs are coupled to a northward shift and amplification of convective activity .
