upsurge
Rapid upward movement
An upsurge is a sudden, strong increase or rise in something.
It applies to quantities, feelings, or activities that grow rapidly: an upsurge in violence, an upsurge of patriotic feeling.
The word emphasizes both the upward direction and the force or momentum of the increase, suggesting something swelling or surging rather than gradually climbing.
As a verb, upsurge means to rise or increase suddenly, though the noun use predominates.
