    A Warm Conveyor Belt is defined as a layer of air which: originates in a relative easterly to southeasterly flow within the lower levels of the troposphere in the ridge area ahead of the front; generally ascends poleward (north to northeasternwarm conveyor belt Often this convection is very weak with updraught velocities of about I m sl, or less The relative humidity of the midtropospheric air entering the system from the west detennines the extent to which potential A 700 a00 XF SWF Fig 3 Model depicting the main features of the largescale flow determining the disAn overview on the concept of Warm Conveyor Beltsposphere The cold conveyor belt (CCB) splits into two branches; an anticyclonic branch, which ascends ahead of the surface warm front from the ABL into the middle troposphere and a cyclonic branch, which remains in the lower troposphere (Schultz 2001) The warm conveyor belt (WCB), experiencing the strongest verticalA 15Year Climatology of Warm Conveyor Belts

    Abstract Warm conveyor belts (WCBs) are important cyclonerelated airstreams that are responsible for most of the cloud and precipitation formation in the extratropics They can also substantially influence the dynamics of cyclones and the upperlevel flow So far, most of the knowledge about WCBs is based on model data from analyses, reanalyses and forecast data with only a few observationalThe warm conveyor belt (WCB) of an extratropical cyclone generally splits into two branches One branch (WCB1) turns anticyclonically into the downstream upperlevel tropospheric ridge, while the second branch (WCB2) wraps cyclonically around the cyclone centreThe dichotomous structure of the warm conveyor beltThe warm conveyor belt is a description that was originally conceived by Browning and Harrold to link the frontal structure in observed cold frontal zones with the largescale flow in cyclones revealed by isentropic relative flow analysis performed using data from the synopticscale network Subsequently, in the identification of WCBsPotential vorticity in warm conveyor belt outflow
