This usually happens when the compressor has too much oil or pressure when turning the compressor on, kind of like a hydrolock but the clutch compensates by making that nose, similar to slippage.
If it happens a lot you should have it looked at by the dealer and tell them it need to sit over night for the condition to happen. I have seen this happen on a lot of Tacoma's and we had to replace the compressor and check the oil level.
