Cambodia hotter than before
Re: Cambodia hotter than before
Wrong for Cambodia and any other (sub)tropical forest.
The evapotranspiration in a forest is much higher than in other areas (fields, urban areas), and it has both a local cooling effect and a regional cooling effect.
Of course, one tree hardly makes a difference apart from the shade it provides, but covering a large area with trees does.

Bogus information. If so, certainly you can provide actual data to back up your claim. And, "an old man told me so" doesn't count.Kammekor wrote: ↑Sun Sep 02, 2018 10:44 amWrong for Cambodia and any other (sub)tropical forest.

A study done in the US for instance, confirming (sub)tropical forests have an overall cooling effect:jmagic wrote: ↑Sun Sep 02, 2018 12:05 pmBogus information.

confirmed by another study in 2015:
https://www.nature.com/articles/ncomms7603
Tropical forests show strong daily cooling of −2.41±0.10 °C because of the consistent cooling during both day and night.
Info about preventing (urban) heat islands by using trees:With lower albedo, forests absorb more shortwave radiation during daytime (positive shortwave anomalies ΔSW in Supplementary Fig. 3a), potentially leading to a warming effect. However, this net energy gain is offset by a greater latent heat loss via higher ET in forests (positive ΔET, Fig. 3b), resulting in a cooling effect.

Re: Cambodia hotter than before
i thought it was hotter than it has been for a while this weekend, it's seemed relatively cool for a few weeks.

Re: Cambodia hotter than before
It only seems hotter because we've had a month or more of cooler weather. 34C is not unusual for September.

Re: Cambodia hotter than before
I love these back up your claim posts, which I can understand. But when you say his is bogus can you back up your statement?

Re: Cambodia hotter than before
Is Cambodia hotter? don't think so yet. Use to regulalry go into 40's in hor season. In fact as far as I can remmber over the last 10 years there has been a lot of variation. I seem to rmember 1 hot season that was only really hot for a couple of weeks and one where it seemd neverending, and bad rainy seasons and not so bad. wetaher is unpredictable because we dont really ubnderstand it
