Graphical user interface for financial activity concerning tropical weather events

A system for offering purchase positions predicting a future first hurricane landstrike resulting from a substantially continuous ongoing natural process starting with a reported precursor tropical storm at sea and culminating in the future first hurricane landstrike, comprising:

• a computer interface module for electronically providing a graphical user interface having first and second portions;
• a database containing 1) a map of geographical areas corresponding to the positions to be offered for purchase, 2) electronically calculated strike probabilities of the future first hurricane landstrike in the geographical areas;
• 3) offer prices for purchasing positions predicting the future first hurricane landstrike in respective geographical areas, electronically calculated at least in part, based on respective strike probabilities and 4) returns on investment based at least in part on respective strike probabilities, that the user can expect on the investment;
• the interface module communicating with the database to display the map in the first portion of the graphical user interface with user selectable portions corresponding to the geographical areas of the map;
• and
• the interface module, in response to a user selecting a user selectable portion and thereby indicating a geographical area for selection, displaying in the second portion of the graphical user interface, a summary of purchase-related offer information for an indicated geographical area, including a strike probability of a future first hurricane landstrike in the indicated geographical area, an offer price for purchasing a position predicting the future first hurricane landstrike in the indicated geographical area;
• and a return that the user can expect on the investment.
