4. ABSTRACT: WEATHER FORECASTING IS THE APPLICATION OF SCIENCE AND TECHNOLOGY TO PREDICT THE STATE OF THE ATMOSPHERE FOR A GIVEN LOCATION.ANCIENT WEATHER FORECASTING METHODS USUALLY RELIED ON OBSERVED PATTERNS OF EVENTS, ALSO TERMED PATTERN RECOGNITION.

5. INTRODUCTION: • THE PROPOSED SYSTEM PROVIDES THE WEATHER OF DIFFERENT CITIES AROUND THE WORLD. • In this system the user can view Weather for which they search for. • The system can track Local and National Weather. • The Proposed system uses open weather API for searching the Weather.

6. WORKING OF THE PROJECT: • THE USER IS ASKED TO ENTER THE NAME OF THE CITY. • USER THEN CLICKS ON SEARCH WHICH FURTHER CALLS THE OPEN WEATHER API • WEATHER CONDITIONS OF PLACE WHICH INCLUDE TEMPERATURE, HUMIDITY, WIND SPEED, WIND DEGREE, CLOUD PCT ARE DISPLAYED

7. IF USER WISHES TO SEARCH WEATHER FOR OTHER CITIES HE CAN RE- ENTER THE CITY NAME IN SEARCH BAR AND PRESS ENTER. • IF USER WISHES TO EXIT, HE CAN SIMPLY CLOSE THE APPLICATION. • IN THIS SYSTEM DON'T NEED TO SETUP WEATHER STATION IN EACH CITY ON EACH COUNTRY TO GET WEATHER INFORMATION. WE CAN GET THOSE INFORMATION INCUDING TEMPERATURE, HUMIDITY ETC. BY USING WEATHER API.

8. TECHNOLOGY USED: PROGRAMMING LANGUAGES: JAVA API: OPEN WEATHER API

9. DATA SOURCE: • OUR SYSTEM USES OPEN WEATHER API TO GET THE WEATHER INFORMATION. • OPEN WEATHER API, THE WORLD'S LARGEST API HUB, IS USED BY MILLIONS OF DEVELOPERS TO FIND, TEST, AND CONNECT TO THOUSAND OF APIS. • THE BACK-END OF THE APPLICATION USES API FROM OPEN WEATHER API, WHICH IS AN OPEN SOURCE AND ENABLES ANYONE TO DOWNLOAD APIS FOR VARIOUS PURPOSES.

14. OUTPUT:

15. CONCLUSION : IN THE ERA OF THE GLOBAL WARMING, RESEARCH IN WEATHER MEASUREMENT, MONITORING AND FORECASTING ARE BECOME MORE AND MORE RELEVANT. THIS RESEARCH DEMONSTRATES THE DESIGN AND IMPLEMENTATION OF AN AFFORDABLE MINI WEATHER MONITORING SYSTEM THAT ENSURES FLEXIBILITY, PORTABILITY, SCABILITY AND USER FRIENDLY OPERATIONS WHICH CAN PROVIDE DATA OF SOME WEATHER VARIABLES INCLUDING TEMPERATURE, HUMIDITY AND PRESSURE.
