The [[electric discharge]] that initiates each [[return stroke]] in a cloud- to-ground [[lightning discharge]].</div><br/> <div class="paragraph">It is a channel of high ionization that propagates through the air by virtue of the electric [[breakdown]] at its front produced by the charge it lowers. The [[stepped leader]] initiates the first [[stroke]] in a [[cloud-to-ground flash]] and establishes the channel for most subsequent strokes of a lightning discharge. The [[dart leader]] initiates most subsequent strokes. Dart-stepped leaders begin as dart leaders and end as stepped leaders. The initiating processes in [[cloud]] discharges are sometimes also called leaders but their properties are not well measured.</div><br/> </div>
