diffluence , auch: difluence

The system was enhanced by diffluence from an upper-level low across the southwestern Atlantic.

By October 13, convection sharply increased as the system entered a region of strong diffluence.

By early on February 7, the circulation had become better defined as it remained in an area of weak wind shear and strong diffluence.

The storm had developed well-defined, upper-level outflow enhanced by diffluence over the system.

However, convection persisted near the circulation over land, believed to have been caused by the process known as upper-level diffluence.

Several flow patterns are characteristic of large deformation: confluence, diffluence, and shear flow.

Steady intensification continued through 22 April 2006 as the storm remained in a region of low wind shear and favourable diffluence.

Located beneath a developing anticyclone, with limited wind shear and enhanced diffluence, the system encountered favorable conditions for development.

Initially moderate upper-level wind shear inhibited organization, while strong diffluence aloft aided in developing convection.

By February 23, deep convection began consolidating around the newly formed center in response to weak diffluence aloft and moderate wind shear.

Little deep convection accompanied the weak system despite being situated within an area of moderate diffluence and weak to moderate wind shear.

The following day, convection began to form around the center of circulation and weak diffluence was noted around the system due to an anticyclone to the north.

Sepat strengthened into a typhoon on the morning of August 14 under still-decreasing wind shear and favourable diffluence.

Upper-level diffluence allowed the convection to persist despite the shearing environment, and an eye-feature developed within the convection.

A small circular area of convection was observed on radar approaching New Orleans, supported by diffluence from an anticyclone over Georgia.

It nearly dissipated on the 24th, but redeveloped on the 26th under an area of favorable upper level winds and good diffluence aloft.

With low wind shear and diffluence aloft, the JTWC remarked the system had a fair chance of developing.

Situated in an area favouring tropical cyclone development, characterised by warm waters, low wind shear and upper-level diffluence, the low was able to quickly strengthen.

Convection persisted around the increasingly well-defined LLCC, and the disturbance continued to consolidate under favourable diffluence.

With a broad upper ridge anchored along the Yucatán coast, diffluence aloft in the vicinity of the disturbance provided focus for the development of scattered convection.

This came after the low level circulation center had started to consolidate as deep convection was being fueled by a poleward diffluence despite being in an area of strong vertical wind shear.

Light wind shear and favorable diffluence allowed the system to strengthen, prompting the JTWC to issue their first advisory on Tropical Depression 22W the next day.

Aided by favorable diffluence aloft, deep convection developed over the center of the system, prompting the JTWC to issue a TCFA on March 22.

Tracking southwest, the storm was named Tropical Cyclone Ami at approximately 0000 UTC on January 12 under favorable upper-level diffluence facilitated by the nearby ridge of high pressure.

Low wind shear and weak diffluence allowed the system to gradually become organized; however, the following day, the Joint Typhoon Warning Center (JTWC) ceased monitoring the system for potential development.
