Mobile portable terminal, communication host apparatus, and weather forecasting system

摘要

A mobile portable terminal may have a sensor section that measures weather information including temperature, humidity, barometric pressure, and sunshine. A first weather information storage section stores the weather information, a first threshold information storage section stores threshold information used to sift the weather information, and a first information computation section computes necessary weather information from the weather information based on the threshold information. A first weather forecast section makes a first weather forecast based on the necessary weather information, a communication section transmits the weather information and receives the threshold information, and a weather forecast output section outputs the first weather forecast.
