"The second important factor is likely a change in pressure. When the heavy rains come in the wild, they are delivered by low pressure storms which provide a relatively sudden change from the high pressure dry conditions before they arrive. It is likely that the frogs can detect this and it could be an additional stimulus for breeding. To mimic this in captivity should not be too difficult: monitor your local weather while the frogs are aestivating and be ready to wake them up after a large rainstorm begins, after a period of at least a few weeks of dry weather."
My suggestion:
Perhaps the addition of a line in this paragraph about purchasing a barometer is in order. Back when I actively bred Anabantoid fish, this was my most indispensable tool for successful breeding. This allows the keeper to get more exact information about barometric pressure drops in their own microclimate. There are many different kinds available, I still use to this day this one:

(This one is available in many places, I use this link only because it gives an excellent breakdown of the unit)
For around 50 USD you get a ton of useful gadgets in one package. The addition of the two remote temperature probes is a real bonus here for critter breeders.
