FORECASTED FROM THE NORTHERN HEMISPHERE LONG PATH-
(TA) Trans Atlantic, (TI) Trans Indian, (TP) Trans Pacific and cross
Equatorial HF propagation conditions greater than
2000 mi/3200 km will be FAIR TO GOOD on 80, 60, 40 and 30 meters, GOOD on
20, 17, 15 and GOOD on 12 and 10 meters.
Note!!! At times propagation conditions on 10 meters will be Good, via the
less predictable Sporadic E (Es) and trans-equatorial (TE) propagation modes
which involve the F2/3 layer.
FORECASTED FROM THE SOUTHERN HEMISPHERE LONG PATH-
(TA) Trans Atlantic, (TI) Trans Indian, (TP) Trans Pacific and cross
Equatorial HF propagation conditions greater than
2000 mi/3200 km will be GOOD on 80, 60, 40 and 30 meters, GOOD TO EXCELLENT
on 20, 17, 15 and GOOD TO EXCELLENT on 12 and 10 meters.
Note!!! At times propagation conditions on 10 meters will be Good, via the
less predictable Sporadic E (Es) and trans-equatorial (TE) propagation modes
which involve the F2/3 layer.

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-
