Warm-water currents are bodies of water originating from areas of the intertropical zone or torrid zones of the Earth, which travel to the polar zones. These currents are formed in intertropical regions, as has already been said, these regions usually have a hot climate. When a current forms in a hot region, it will take these characteristics with it and influence distant locations. This is the case with the Gulf Stream that reaches the European continent and softens the climate of this region.
