What 3 factors caused hurrricane sandy?

Hurricane Sandy was primarily influenced by three main factors: warm ocean waters, which provided the energy needed for storm development; a combination of atmospheric conditions, including a dip in the jet stream that allowed the storm to track westward; and the presence of high-pressure systems that steered Sandy toward the northeastern United States. Additionally, climate change may have contributed to the intensity and unusual path of the storm. These factors combined to create the conditions that led to Sandy's significant impact.
