Experimental Climate Monitoring and Prediction for Maldives – August 2016


HIGHLIGHTS

In July, northern and central islands received up to 200 mm above average rainfall while southern islands received up to 100 mm below average rainfall. The amount of rainfall received by northern and central islands is the highest amount received in past six years in these regions. Since the last week of July a decrease in rainfall throughout the country was visible and the first week of August was mostly dry. Heavy rainfall was received by central islands in late August. During August, the sea and land temperatures remained warmer than climatological. The wind speeds were high due to the SW Monsoon.
Northern islands received up to 200 mm rainfall in July

Experimental Climate Monitoring and Prediction for Maldives – July 2016


HIGHLIGHTS

The entire country received up to 200 mm less than average rainfall in June 2016. In July, northern and central islands received up to 200 mm above average rainfall while southern islands received up to 100 mm below average rainfall. The amount of rainfall received by northern and central islands is the highest amount received in past six years in these regions. Since the last week of July a decrease in rainfall throughout the country was visible and the first week of August was mostly dry. Dry conditions shall prevail in the second week of August as well. ENSO models predict likely development of La Niña conditions during August or September.

Experimental Climate Monitoring and Prediction Highlights for Maldives – July 2016


HIGHLIGHTS

Heavy rainfall was observed throughout the country during the first week of July with Central and Southern islands receiving rainfall up to 40 mm. During the second week of July the rainfall decreased gradually with only Central islands receiving light rainfalls. IRI CFS model predicts up to 50 mm total rainfall for Northern islands and less than 50 mm for Central islands during 11th – 16th July. GFS (T574) model predicts rainfall up to 10 mm for entire Maldives and a gradual increase in rainfall for Northern islands up to 40 mm in the coming week.

Experimental Climate Monitoring and Prediction for Maldives – June 2016


HIGHLIGHTS

Heavy rainfall was seen in the entire Maldives in May 2016 and the rainfall gradually decreased during the first three weeks of June. In northern and central islands, rainfall ceased by mid-June and in southern islands, rainfall ceased by early June and increased until mid-June up to 60 mm. NOAA CFS model does not predict heavy rainfall in the next few days in any part of the Maldives. The IRI predicts La Niña conditions by late June which shall give a drier tendency to rainfall in central and south central regions. In Northern and southernmost island rainfall shall have a wetter tendency. The sea around the Maldives show a much reduced level of warming.

Experimental Hydro Meteorological Highlights for the Maldives- June 2016

HIGHLIGHTS

Up to 20 mm rainfall was seen in the Northern islands of the Maldives while the rest of the country remained dry during 29th May- 12 June 2016. IRI CFS model predicts up to 50 mm total rain in during 13th- 18th June in northern and central islands. Heavy rainfall is not expected in any part of the country during this period.

Can Maldives reefs recover from El Nino?

Original Article:Link
 by Hassan Moosa

The reef of Villingili Island, just a few minutes away from Malé, has suffered damage from reclamation, dredging and harbor construction. It took another hit this year when warmer ocean temperatures, caused by the El Nino, killed a majority of its coral. On a recent dive, I found a graveyard on the island’s reef slope. A slimy layer of brown green algae covered the dead corals, while the few that still held out were bleached white. Some had startling spots of purple and pink, indicating a former more colorful appearance.

Experimental Climate Monitoring and Prediction for Maldives – May 2016


HIGHLIGHTS

Extraordinary Rainfall close to 60 mm/day was observed in and around the Maldives which caused flooding in many islands. The highest average daily rainfall is typically 7 mm/day. The sea around the Maldives also had rainfall excess of 100 mm/day. This high rainfall ceased on the 20th and no heavy rainfall was seen in the Maldives since that day. The rainfall observed in the first weeks of May is the highest rainfall received by Northern and Southern islands this year. The first four months had been dry in the Northern Maldives and therefore this rain helped to lessen the cumulative rainfall deficit in this region since last December, Global weather model prediction does not expect any extreme rainfall in the remaining days of this month. The Sea surface around the Maldives and Sri Lanka has become cooler and its Only 0.5 0C above average This had risen up to 1 0C in the previous months while the El Niño was strong. El Nino is now moderate and is expected to become neutral by the end of this month.
