FORECASTED GLOBAL LIGHTNING NOISE (QRN)-



Northern 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.

Northern 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.

Northern 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.



Southern hemisphere low latitude regions can expect 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.

Southern hemisphere mid 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 high latitude regions can expect LOW TO MODERATE thunderstorm lightning induced QRN tied to winter

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
