The third convergence zone was a good hundred miles off.

He has to be way out there, skipper, like the third convergence zone.

The boundaries where two air masses meet are known as convergence zones.

Turtles spend most of their first five years in convergence zones within the open ocean.

The tropical convergence zone was clear against the blue.

Four of the five storms developed from the intertropical convergence zone.

"Do we have a convergence zone that would allow us to hear something from another submarine op area?"

Areas of clouds and rainfall appeared to be focused along this convergence zone.

Most of the provinces lie within, or very near the Antarctic convergence zone.

The location of the intertropical convergence zone varies over time.

The trailing convergence zone was referred to as the squall line or cold front.

The wave remained very close to the intertropical convergence zone for the next several days without any further development.

Eventually, the convergence zone overlapped somewhat with the warm patch to the north.

The contact's intermittent, so I think we're receiving the sound source via a convergence zone.

Those clusters are activated simultaneously by feedback firing from a convergence zone.

Their erstwhile contact would now be exactly two convergence zones away and should have been easily detected, given known water conditions.

On Earth, the intertropical convergence zone is confined to the tropics.

He'd had to stay close, within direct-path range, not allowing himself to come into a sonar convergence zone.

One critical question about convergence zones remains unanswered.

"My guess," the sonar supervisor added, "is that it's in the second convergence zone from us."

Another phenomenon in the deep sea is the formation of sound focusing areas, known as Convergence Zones.

Convergence zones also occur at a smaller scale.

It was impossible for convergence zones to occur in the south Barents Sea.

The water was not deep enough yet for convergence zones, and they were beginning to get low-frequency background noise from the icepack.

He was not in a convergence zone."
