FORECASTED GLOBAL LIGHTNING NOISE (QRN)-
Northern hemisphere low latitude regions can expect VERY HIGH thunderstorm

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.
