Con la presencia del Director de Seguridad y Operaciones Marítimas Contraalmirante LT Iván Valenzuela Bosne, del Director de la Dirección Meteorológica de Chile, Guillermo Navarro Schlotterbeck, representantes de la Organización Meteorológica Mundial y delegaciones de 24 naciones se realizó la Ceremonia inaugural del "V Taller Internacional de Oficiales Meteorológicos de Puerto de la Comisión Técnica Mixta de Oceanografía y Meteorología de la Organización Meteorológica Mundial".

En la oportunidad, en su condición de Autoridad Marítima, el Contraalmirante Iván Valenzuela hizo uso de la palabra para dar la bienvenida a las delegaciones de las 24 naciones participantes. En su intervención, el Almirante Valenzuela destacó el trabajo realizado por el Servicio Meteorológico de la Armada de Chile, en procura de lograr la adhesión del mayor número de capitanes de naves mercantes, de pesca industrial, de pasajeros, comandantes de buques y deportistas náuticos entre otros, para contar con un mayor flujo de información que permita la confección de pronósticos. Lo anterior cobra mayor validez si se considera que es de responsabilidad del Servicio Meteorológico el área denominada Metarea XV.

As an archipelago in Western North Pacific, the Philippines is exposed to tropical cyclones of varying intensity and impacts at an average frequency of 20 tropical cyclones a year. To mitigate or reduce the damages caused by this disastrous phenomenon, the Philippine Weather Bureau, the national meteorological-hydrological service now known as Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA), established the Tropical Cyclone Warning System (TCWS).

In 1950’s, the TCWS involved 10 warning levels: Public Storm Warning Signal (PSWS)# 1 to PSWS #10. Basically, the warning system was designed for mariners at sea. Visual storm warning signs in the form of cones and cylinders are hoisted prominently on masts in ports. Night signals are in the form of red and white lamps. In 1970’s, the number of warning levels was reduced from 10 to three (3) using the three WMO tropical cyclone category as basis. The warning levels then are: PSWS #1:  max winds <63 kph for Tropical Depression; PSWS #2:  max winds 64 -117 kph  for Tropical Storm; and PSWS #3: max winds >118 kph for Typhoon. In 1997, there was motion to upgrade the warning levels to four (4) for the reason that the number of warning signals is inadequate for strong typhoons. Hence,  the signals used was PSWS #1 to PSWS # 4 with the addition of time element: PSWS # 1: Winds 30-60 kph -expected in at least 36 hrs; PSWS # 2: Winds >60-100 kph -expected in at least 24 hrs; PSWS # 3: Winds >100-185 kph -expected in at least 18 hrs; and PSWS # 4: Winds >185 kph -expected in at least 12 hrs.  Some changes such as addition of meteorological conditions, impacts of the winds and precautionary measures were made later in 2010.

The Himawari-8 geostationary meteorological satellite managed by the Japan Meteorological Agency (JMA) began operation at 02 UTC on 7 July 2015, replacing the previous MTSAT-2 operational satellite. The true-color composite imagery at 02 UTC captured three typhoons in the Pacific.

Himawari-8 was launched using H-IIA Launch Vehicle No. 25 on 7 October 2014 from the Tanegashima Space Center, and JMA subsequently conducted testing and checking of the satellite and related systems. During the commissioning phase, Himawari-8’s capacity for superior earth monitoring with multi-band, high-resolution and high-frequency observation was verified. JMA firmly believes that Himawari-8 will open the door to a new generation of satellite meteorology, and that it will contribute to the prevention and mitigation of weather-related disasters in the East Asia and Western Pacific regions as past satellites have done.

The simplest way to see real-time Himawari-8 imagery is to access the following website where JMA provides Himawari-8 imagery in JPEG format for various regions in various bands including RGB composite products updated every 10 minute.

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.

The Met Office and the World Bank Group sign a Memorandum of Understanding.

The Met Office and the  World Bank Group signed a Memorandum of Understanding (MOU) in Washington DC this week to signal their shared purpose to support developing countries to address climate change. The collaborative approach will help to increase resilience, reduce disaster risk, improve national and regional early warning systems and strengthen the capacities of regional and national hydro-meteorological services.

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...)

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 .
