One of the ways of calculating the energy that drives a hurricane is to look at the amount of latent heat transport so condensation then rain etc. Imagine the amount of energy transport in that front |

Actually Naut that is a function of daylight length change.
We in NZ in the north have small climate shift peak summer 24C average peak winter average 15C trees always confused but because of latitude daylight change is to little 36 south.
we also have trees like oaks full spring and trees still shedding leaves

It has stopped growing just like that left it 9 days since midweek last week and it hardly needed mowing. Same temperatures same rain (and sprinklers). It's like someone threw a switch. I can't think it is just the equinox. Did anything happen with the sun last week? |
