Re: Red Sky at Night - The Science Behind Weather Sayings
A nice read, Dennis. But must remember that these are local sayings.
They can be vastly wrong in a different area:
1. "Red sky at night, shepherd's delight; red sky in the morning, shepherd's warning"
Only in higher latitudes. The tropics can be any colour. But it does feel more cheery
2. "Three days rain will empty any sky"
Any system over anywhere in the world will have moved by 3 days. So its a no brainer.
3. "When the wind is out of the east, tis neither good for man nor beast"
Local weather lore. Here and now it would be SW, run; N run screamin... East wind here, now, is just what we want
4. "In the morning mountains, in the afternoon fountains"
Building convection in clouds during the day can in many areas mean rain later, but via thunderstorms not long bouts of rain from frontal activity in the tropics.
5. "If a circle forms 'round the moon, 'twill rain or snow soon"
In the tropics is a fair weather predictor not rain!!
They can be one of 3 things: Coronas - Alto Stratus fair weather predictor everywhere - there is generally some colour in the rings; Haloes - generally white rings in Cirrus may be a predictor in high latitudes of a front but too often wrong to be of use; Sun Dogs - Cirrus - a halo with 2 bright reflections on the horizontal plane that appear to be mini suns. High latitudes and not reliable to predict a front.
