ERICA, or the Experiment on Rapidly Intensifying Cyclones over the Atlantic, is a scientific field project that started in the winter of 1988/1989. Its aims were to better understand the processes involved in rapid cyclogenesis, and so improve understanding and forecasting of the situations that cause it.

Erica , is a genus of roughly 860 species of flowering plants in the family Ericaceae. The English common names "heath" and "heather" are shared by some closely related genera of similar appearance. The genus Calluna was formerly included in Erica – it differs in having even smaller scale-leaves (less than 2–3 mm long), and the flower corolla being consisting of separate petals. Erica is sometimes referred to as "winter (or spring) heather" to distinguish it from Calluna "summer (or autumn) heather".
