How do you explain why the A/S increases on thermal entry?

The way I look at it is, you're flying at a speed on relatively constant
airmass during cruise. Then when you enter the thermal you're entering a
gust of wind that is moving upward. So that gust of wind is going to
accelerate you, but at first it must gain enough force. While it's gaining
that force it's just blowing extra wind that the instrument translates as
airspeed. I could be wrong but this is how I see it in my mind.

Just got asked this question, didn't have a quick and easy answer. How
do you explain it?

Does the airspeed really increase on thermal entry ??? I am not
convinced of that.

I think the opposite is true : when the airspeed increases, due to entry
into a thermal, turbulence or any other reason, you
TE-compensated-variometer believes there is a lift !

Q. Pourquoi ne faut-il pas répondre au-dessus de la question ?
