FORECASTED GLOBAL LIGHTNING NOISE (QRN)-

Northern hemisphere low latitude regions can expect VERY HIGH thunderstorm 
lightning induced QRN tied to winter season proximity

to the Inter-Tropical Convergence Zone (ITCZ) as well as cold/warm/occluded 
fronts and associated extra-tropical cold core low

pressure systems.

Northern hemisphere mid latitude regions can expect HIGH TO VERY HIGH 
thunderstorm lightning induced QRN tied to winter

season cold/warm/occluded fronts and associated extra-tropical cold core low 
pressure systems.

Northern hemisphere high latitude regions can expect MODERATE TO HIGH 
thunderstorm lightning induced QRN tied to winter

season cold/warm/occluded fronts and associated extra-tropical cold core low 
pressure systems.

Southern hemisphere low latitude regions can expect VERY HIGH thunderstorm 
lightning induced QRN tied to summer season

proximity to the Inter-Tropical Convergence Zone (ITCZ) and tropical warm 
core low pressure systems.

Southern hemisphere mid latitude regions can expect HIGH TO VERY HIGH 
thunderstorm lightning induced QRN tied to summer

season cold/warm/occluded fronts and associated extra-tropical cold core low 
pressure systems, as well as tropical warm core low pressure systems.

Southern hemisphere high latitude regions can expect MODERATE TO HIGH 
thunderstorm lightning induced QRN tied to summer

season cold/warm/occluded fronts and associated extra-tropical cold core low 
pressure systems.

Lightning Induced Noise (QRN) Forecast Scale-

Very High >+1 db Over S9

High- S7-9

Moderate- S4-6

Low- S1-3

None- S0
