There is a negative 00, it just happens to be equal to the normal zero. For each real number aa, we have a number −a−a such that a+(−a)=0a+(−a)=0. So for 00, we have 0+(−0)=00+(−0)=0. However, 00 also has the property that 0+b=b0+b=b for any bb. So −0=0−0=0 be canceling the 00 on the left hand side.

The definition of positive (resp. negative) is that a>0a>0 (a<0a<0), and it's obvious that 00 satisfies neither. – YoTengoUnLCD Sep 5, 2016 at 13:41 @YoTengoUnLCD you are rigth. – Jorge B.

You see negative zeroes in things like 5-min obs that do that Fahrenheit to Celsius to Fahrenheit thing, as -18C = -0.4F which shows up as -0 on there.

paweather Posted February 22, 2022 Share Posted February 22, 2022 WSW event? Link to comment Share on other sites More sharing options...
CarlislePaWx Posted February 22, 2022 Share Posted February 22, 2022 Boy, the 12 nam is certainly interesting for the upcoming winter event. Breaking it down, the precip starts as primarily sleet around 0Z. It sleets for 3-4 hours until around 4z, accumulating roughly 0.7". It then changes to freezing rain with only light amounts of around 0.1" (not accrual) between 4z and 13z. It then changes to rain for the remainder of the event, which is only another 3-4 hours, with less than 0.1". Total qpf for the event is about 0.4" of liquid. Temp remains between 32-33 until the event ends by 16z. Then the temp goes up to the upper 30's for the afternoon before crashing back down below freezing by around 23z. The only interesting (frozen) part of the storm will be the sleet for several hours Thursday evening (imo). This breakdown is for the area roughly between me and MDT. 1 Link to comment Share on other sites More sharing options...
