WEB BASED WEATHER VISUALIZATION AND FORECASTING SYSTEM

Abstract

The visualization and forecasting system for northern areas of Pakistan has been developed to help users to visualize historical temporal weather data in their respective region. This system is designed with the goal to supplement the productivity of already available website of Pakistan meteorological department. The system is flexible enough to visualize current data. It also presents multiple weather scenarios to visualize weather data. The weather data which is visualized is available from 1980 to 2010 from different weather stations of Pakistan, maintained by the Pakistan Meteorological Department. Two types of weather forecasting has been implemented. Short term weather forecasting has been done to predict the daily forecast and Long term forecasting uses linear regression for predicting the weather trends from year 2011 to 2026 based on real-time data. The system is designed in such a way that it can present data in user friendly and comprehensible graphical formats and plots. The results for long term forecasting show that in next ten years rain fall will decrease effectively in the northern areas of Pakistan, whereas, an increase in the humidity has been observed after carefully reading the forecasted plots.
