simply over-ride the autothrottle manually when required.
A Boeing 737 Memorandom from about 15 years ago advised against forcing the autothrottles against their clutch motors where the autothrottles are attempting to maintain the MCP speed. I am a bit vague but the figure given by Boeing was something like any more than 6 lbs manual pressure against the throttle levers while the autothrottle system is trying to do its thing, is likely to cause eventual damage to the clutch motors.

This would suggest that if you are unhappy with the performance the autothrottles are trying to give you in certain weather conditions, then it is better to completely disengage the autothrottle system and use manual throttle control, rather than "fight" the automatic system? Seems logical to me, anyway
