According to SMU Associate Professor of Humanities Winston Chow, who researches on the relationship between urban spaces and the climate, landspouts are uncommon in Singapore. He said, "While these winds usually form on very hot days, they can also occur when very strong updrafts from the surface occur as thunderstorm clouds develop in size." Assoc Prof Chow noted, "Landspouts that can cause damage are thankfully relatively infrequent over land. They are usually more common over water as waterspouts."
