Between June 8 and June 13, experts from National Meteorological Center of China Meteorological Administration (CMA) and National Meteorological Information Center went to Bangladesh Meteorological Department to provide technical services in forecasting, data system and communication system.

The expert team did a lot of work in Bangladesh, such as invested and maintained the relevant system, upgraded the MICAPS, set up SWAP system, replaced shortcut system of FY-satellite, imported data of FY2G and configured system for satellite switch, and provided training and Q&A session for engineers and weatherman to maintain systems and use the client-side of MICAPS. They also learnt about the process of forecasting in Bangladesh in order to provide further assistance. Their work were thanked and welcomed by leaders of Bangladesh Meteorological Department.

L'été météorologique, qui commence le 1er juin et s'achève à la fin du mois d'août, correspond à la période la plus chaude de l'année dans l'hémisphère Nord. En moyenne, sur l'Hexagone, la température normale* de la saison est de 19,9°C.

Petit tour d'horizon des étés records en matière de température :

Depuis 1900, c'est l'été 2003 qui a été sans conteste le plus chaud, avec une température moyenne de 23,1°C, soit 3,2°degrés au-dessus la normale. L'été 1956 s'est révélé être le plus froid avec une température moyenne de 17,3°C, soit 2,6 degrés sous la normale.
Les deux étés les plus chauds (2003, 2006) se sont produits au XXIe siècle, 2003 étant de loin le plus exceptionnel (2 degrés au-dessus de 2006...)

Mayo, es como promedio el primer mes del periodo estacional lluvioso (mayo-octubre) en Cuba, y se encuentra entre los de mayores acumulados en general para el país. En esta ocasión, finalizó con un 41 % del territorio nacional con déficits en sus acumulados. De ellos, el 6 % correspondió a déficits catalogados de extremos a severos, un 11 % a moderados y el 24 % a débiles. Se ubican en la región Occidental del país los más significativos, siendo las provincias de Pinar del Rio, Artemisa, La Habana y Matanzas, las más afectadas, no obstante se aprecian en el resto del país pequeñas zonas con déficits pero de menor cuantía. Los municipios con mayores déficits reportados fueron: San Cristóbal, Jovellanos, Los Palacios, Candelaria, Unión de Reyes, Pedro Betancourt, Yateras, Bahía Honda, Limonar y Peric.

Meteorological Service Singapore (MSS) is forecasting that Singapore and the surrounding region can expect a drier and warmer than usual Southwest Monsoon season (June – September/early October) this year. This is partly due to the prevailing moderate El Niño conditions in the equatorial Pacific Ocean, which are likely to further develop in the months ahead.

With fewer rain days experienced this month, the total rainfall for June 2015 (as at 25 June 2015) recorded at the Changi climate station is 38% below the long-term average. Warmer days and nights have also been experienced in recent days. The average daily maximum and minimum temperatures for June 2015 (as at 25 June 2015) are 31.9°C and 26.5°C, about 0.6°C and 1.7°C above the long-term average respectively .

Agreements between the Chinese mainland and Taiwan to cooperate in meteorological and seismic monitoring took effect on Wednesday.

Both sides are ready to implement the two agreements, according to briefs exchanged between the mainland-based Association for Relations Across the Taiwan Straits (ARATS) and the Taiwan-based Straits Exchange Foundation (SEF).

The on-going El Niño is showing signs of strengthening.  Recent observations indicate that the Sea Surface Temperature over the Niño 3.4 region has manifested significant warming since April 2015 and expected to be at moderate level by end of June 2015.  Computer models suggested that the current El Niño may last until the early months of 2016.

Impacts to the Philippines include below normal rainfall condition persisting in many parts of the country and late Southwest Monsoon development leading to the late onset of the rainy season.  Current weather analyses already shows signs of gradual development of southwest monsoon and the migration of the Intertropical Convergence Zone (ITCZ) over the Philippines, as manifested by increase in thunderstorm activities mostly in the afternoon.

Según las recientes observaciones y modelos utilizados por diferentes centros internacionales de predicción climática, se mantiene una alta probabilidad, que el fenómeno El Niño continúe para el trimestre junio-julio-agosto; persistiendo además, la probabilidad de que el evento se extienda en lo que resta de 2015.

Durante el mes de mayo, el océano Pacífico Tropical, presentó un incremento moderado en su temperatura (anomalías positivas), alcanzando valores de hasta 2.5°C por encima de los promedios normales, en zonas cercanas a las costas suramericanas. A ésta condición, se ha sumado el debilitamiento de los vientos alisios, existiendo en este momento un mayor acoplamiento entre el océano y la atmósfera, características que reflejan la permanencia del fenómeno 'El Niño'.

Information on recent earthquake activity in the eastern Reykjanes peninsula

In recent weeks, increased seismic activity has been detected on the Reykjanes peninsula, including a M4 earthquake in late May close to lake Kleifarvatn, which was felt widely in the capital region. Following such earthquakes, stress conditions in the shallow crust can be changed in the surrounding region.

An analysis of micro-earthquakes in the region indicates possible instabilities in the crust between lake Kleifarvatn (Krísuvík) and Ölfus (the region of the 2008 earthquakes, close to Hveragerði). Deformation measurements in recent years also indicate possible stress accumulations in the region, which might be released as a larger earthquake. Historic recordings show that earthquakes in that region can be up to M6.5. The last earthquakes of M>6 were in 1929 and 1968. Both of these events caused no major damage in the capital area. In modern times, however, urban settlements have spread closer to historically active earthquake faults.
