WHAT IS AMO?

Atlantic Multidecadal Oscillation — a 60-80 year cycle of North Atlantic SSTs.

When AMO is WARM:
· More intense Atlantic hurricanes
· Drought in US Midwest
· Wetter Sahel (Africa)
· European summer warmth

When AMO is COOL:
· Fewer, weaker hurricanes
· Wetter US Midwest
· Drier Sahel

KEY STATIONS

1926 — WARM peak · Hurricane season amplified

1970 — COOL trough · Atlantic quiet period

1995 — WARM onset · Hurricane Opal / era begins

2005 — Katrina peak · AMO+ENSO combo

~2030 — FLIP WATCH · projected cool onset

HURRICANE AMPLIFICATION

AMO WARM = HURRICANE AMPLIFIER

AMO warm phase raises North Atlantic SSTs by +0.3°C to +0.5°C. This extra energy feeds Atlantic hurricane intensification.

During AMO WARM (1995–now): 9 of 12 most destructive Atlantic hurricane seasons occurred.

AMO WARM + El Niño = Cat 4-5 risk window → see hurricane showcase

CURRENT STATE — DAY 92

AMO PHASE: WARM (since 1995)

Index: +0.2 to +0.4
Duration: ~30 years (typical warm phase = 30-40yr)
Flip horizon: ~2025-2035 watch window
Hurricane season: ACTIVE AMO WARM PHASE

DIAMOND SIGNALS

💎 HURRICANE WINDOW — AMO warm × El Niño = amplified season

💎 PHASE FLIP WATCH — AMO cool onset = insurance recalibration

💎 Reinsurance — AMO warm = reinsurance floor compressed

💎 Nat Gas — AMO cool flip = Atlantic storm reduction = demand drop
