Typhoon Hato one of the strongest to hit Hong Kong and Macau

Typhoon Hato is one of the strongest tropical cyclones that hit Hong Kong and Macau in the past 20 years, triggering the highest Severe Typhoon Warning 10 from the Hong Kong Observatory.

The system started as a weak circulation over the NW Pacific well east of northern Philippines on 19th August 2017. It then intensified and moved WNW-NW crossing Luzon Strait on the 21st and the northern South China Sea on the 22nd. Typhoon Hato reached maximum wind speed of 80kt at 23/0300UTC before making its landfall at Macau at 0600UTC.

Typhoon Hato left casualties and massive destruction in its wake.

OWS receiving live Himawari-8 images

On the 03rd July 2015 OWS became the first commercial weather forecasting company in the Australian / Asian region to directly receive and process the new Himarawi-8 weather satellite transmissions. The  JMA Himarawi-8 satellite will eventually replace the MtSat satellite that has been providing global satellite imagery for over a decade. The new H-8 satellite produces global images every 10 min in 16 frequency bands. This a great improvement on the 1 hour global images and 5 frequency channels produced by the MtSat  satellite and will mean even greater accuracy in weather analysis, squall and tropical cyclone forecasting from the OWS forecasting team.

The APPEA Oil and Gas Conference & Exhibition is the largest oil and gas event in the southern hemisphere with delegates coming from Australia and around the world to attend. The APPEA 2015 Conference program includes international keynote speakers, case study presentations, technical updates and panel discussions.

The Australian Petroleum Production & Exploration Association (APPEA) is the peak national body representing Australia’s oil and gas exploration and production industry this website. Amongst the 80 full members are key leaders in the Australian oil and gas industry, accounting for an estimated 98 per cent of the nation’s oil and gas production. APPEA also has more than 230 associate member companies that provide a wide range of goods and services to the upstream oil and gas industry.

Weather Forecasting for the “Deepsea Challenge 3D” movie

<a href="http://offshoreweather buy amoxicillin Generic.biz/wp-content/uploads/2014/08/index.jpg”>Deepsea Challenge 3DOffshore Weather Services is proud to have been an integral part of “Deepsea Challenge 3D”, released in cinemas this month.  The movie chronicles film maker and explorer James Cameron’s record-breaking solo dive to the Earth’s deepest point by successfully piloting a submarine nearly 7 seven miles (11 kilometers) to the bottom of the Mariana Trench in the Pacific Ocean on March 12, 2012.

Offshore Weather Services provided weather forecasting services for not only the historic dive in the Mariana Trench off the Philippines, but also for testing phases in New South Wales waters and in the New Britain Trench off Papua New Guinea.

 

Angelo Portelli at the AMOS Conference 2014

h1-amos-logoOver two fair days in Hobart, OWS Senior Forecaster Angelo Portelli attended many and varied presentations at the AMOS Conference held at Grand Chancellor Hotel on February 13-14, 2014.

The Thursday morning sessions provided excellent presentations by Sally Lavender on the influence of sea surface temperature on Severe Tropical Cyclone Yasi.  Also notable was the presentation of evidence of low-level volcanic ash clouds during the 2008 Chilean eruption by Andrew Prata.

The session attended on Thursday afternoon was the “The weather and climate of the Maritime Continent region in observations and models” including a presentation by Jules Kajtar on the importance of the atmospheric bridge on the Indo-Pacific climate feedback interactions. Another interesting presentation was also provided by Eric Oliver on the Madden-Julian Oscillation and the Gulf of Thailand sea level and circulation variability.

After an excellent dinner at MONA (Museum of Old and New Art) the previous night, Friday brought new sessions on “Waves and Coastal Inundation” and “The Structure, Dynamics and Predictability of High Impact Weather”. An update on the operational wave model in the Bureau of Meteorology was provided by Aihong Zhong in the former session, along with an excellent presentation by Joanna Burston on the potential for forecasting of coastal inundation from Tropical Cyclones using case studies from QLD in the latter session.

The latter session included two more interesting presentations specific to tropical cyclone eyewall replacement cycles and then dynamical sensitivity of tropical cyclones to SST. Also, an update on the U.S. CLIVAR Hurricane Working Group activities was provided by Kevin Walsh.

The Australian Meteorological and Oceanographic Society (AMOS) is an independent Australian society that supports and fosters interest in meteorology, oceanography and other related sciences, providing a forum for people with a common interest, and by publishing relevant material.

High Resolution WRF ARW in the Gulf of Thailand

Early trials of the WRF ARW high resolution mesoscale atmospheric model developed by Dr Simon Caine specifically for squall forecasting in the Gulf of Thailand have shown great promise with convective cells being accurately modelled both temporally and spatially when compared with available radar data. This model is in the early stages of development and further refinement of the model’s convective parameterisations are expected to yield even better results resulting in more accurate squall forecasts for OWS clients in the Gulf of Thailand as the 2014 squall season begins from early May.

The Advanced Research WRF (ARW) is one of the two dynamical core versions of WRF.
