What is Earth Disaster Decade?
Earth Disaster Decade is a simplified 10-year hurricane campaign that turns Atlantic season setup choices into an infrastructure and preparedness strategy game. You allocate a Risk Budget, choose conditions and resilience cards, and then watch the monthly simulation decide whether storms form, strengthen, miss land, or cause damage.
How the 10-year hurricane campaign works
Each campaign lasts 10 years, and each year contains 12 monthly turns from January through December. The game resets the yearly Risk Budget to 100 points, lets you build a scenario, runs the season month by month, and then shows a yearly summary before the next year begins.
How hurricanes form in this simplified model
The model combines seasonality, storm seeds, warm ocean water, wind shear, Saharan dust or dry-air suppression, ENSO-like patterns, steering signals, exposure, resilience, and a monthly random event. Strong African easterly waves matter more in August and September, Gulf disturbances matter more from June through October, and off-season setups are treated as less realistic.
Why these factors matter
Warm Atlantic water and very warm Gulf water can support formation and intensification. Wind shear can tear storms apart. Saharan dust and dry air can suppress activity unless the player invests in suppression-reduction conditions. Steering and exposure patterns decide whether a storm threatens the Gulf Coast, Florida, or the Northeast, while preparedness and resilience reduce impact instead of increasing destruction.
What the Science Score means
Science Score measures whether the scenario matched the month and the simplified Atlantic hurricane season. Realistic timing, sensible card combinations, and seasonally appropriate storm seeds improve the score. Unrealistic off-season setups lower it, especially when strong seeds are used in months that rarely support them.
What the Impact Score means
Impact Score represents broad property damage, infrastructure stress, flood damage, storm surge pressure, power disruption, and recovery burden. It does not track deaths or casualty scoring. The focus is education about risk, exposure, and resilience.
Why this is not a real forecast
This is a game system, not a forecast model. It does not use live weather data, official advisories, or a physical numerical weather model. The random event probabilities are game-design values meant to make the campaign readable and replayable.
Why the simulator uses broad cost ranges
Recovery Cost is shown as a broad range instead of fake precision because infrastructure damage estimates are uncertain and scenario-based. Using ranges keeps the output more honest than pretending the simulator can calculate an exact dollar figure from a simplified educational setup.
