S.Gan Climate of Maldives
6 Climate of Maldives Maldives has two seasons: • Wet season (southwest monsoon extending from mid-May to November). • Dry season (northeast monsoon extending from January to March/April) Climate of Maldives… • In these two seasons the temperature variations are very small as they are moderated by the sea (99% of Maldives is sea area) • Hence Maldives experience a maritime climate. Rainfall Climatology
9 Rainfall variability
10 Monthly rainfall
North NE Monsoon: 16%
Central NE Monsoon: 28%
South NE Monsoon: 36%
11 Spatial mean annual rainfall
12 North East Monsoon Rainfall (Jan and March)
13 Southwest Monsoon Rainfall (Jul, Sept and Nov)
14 Extreme rainfall events: rainfall > 50mm
Showing decreasing trend (no of days with rainfall threshold value of 50mm decreasing) In all the years and for all the locations at least 2 rainfall events >50mm Indicates both bad and good news!!! Prediction System
16 Tools used for rainfall prediction
17 Satellite Application
CMAcast FY2 E Satellite image Receive images every 30 min IR, Vis, Water vapor & 3D images 19 Prediction system Based on these and other products, we provide 5 day forecast…and seasonal forecast… We also use IMD, RIMES and WMO lead centre products for issuing seasonal forecast

Maldives Meteorological Service
Regional Integrated Multi-Hazard Early Warning System
3 Climate Service: Seasonal Climate Prediction in the Maldives • Since then every year we issue seasonal rainfall forecast • Last year issued seasonal forecast 3 times
22 Climate Service: Seasonal Climate Prediction in the Maldives • This year, during first National Climate Outlook Forum (NCOF: WMO), Southwest Monsoon seasonal rainfall forecast was shared with stakeholders.
23 Seasonal Climate Prediction in the Maldives: • So far we have not issued seasonal forecast for northeast monsoon season. • However, it is very important to issue seasonal forecast for north east monsoon season. • During this season many islands of Maldives experience shortage of rainwater.
