Their study attempts to show how fall speed and intercept parameters can influence the tropical cyclone intensity.

After starting a phase of rapid deepening, Kalunde attained cyclone intensity the next day.

The cyclone's intensity was estimated to have reached cyclone intensity from 29 to 30 July.

The system reached cyclone intensity the following day.

Tropical cyclone intensity was reached on January 2 and intensification proceeded at a fairly rapid rate.

There is a limit on tropical cyclone intensity which is strongly related to the water temperatures along its path.

The report concluded the observed increase in tropical cyclone intensity is larger than climate models predict.

The low persisted into March but did not reach cyclone intensity.

The system achieved cyclone intensity on May 22.

Early on 18 March, Lua weakened below tropical cyclone intensity.
