Welsh golfer Bradley Dredge still led the Qatar Masters after the renowned gusts returned for the second round, but he had company.
Eight others caught him to create a nine-way tie for the lead, a European Tour record.
The last time nine players were tied on top was after the first round of the 1997 Wales Open, but this was the first time in Tour history so many led after 36 holes.
Dredge was the only one of the nine not to finish under par. His even-par-72 gave him a halfway total of eight-under-136.
The gusts made playing more difficult in the afternoon, and only three players from the afternoon groups - South Korea's Wang Jeunghun (67), South Africa's Jaco van Zyl (69) and Thailand's Kiradech Aphibarnrat (70) - managed to make a move.
