WebbThe probability calculator finds the probability of two independent events A and B occurring together. Two events are independent events if the occurrence of one event does not affect the probability of the other event. If A and B are independent events, then the probability of A and B occurring together is given by
WebbSTI is an index representing the probability of occurrence of a temperature value when compared with temperature values on a longer period. Positive and negative STI values indicate temperatures above and below the median temperature of the long-term time period respectively. It can be used to identify anomalously hot and cold periods.
