Weather and East Coast Lows

Do you understand the weather forecasts ? This weekend's East Coast Low is hard to miss, see http://www.abc.net.au/news/2016-06-04/storm-warning-east-coast-braces-for-flooding-strong-winds-rain/7477244 for details.

Attached are images captured on Friday by Robin sourced from the BOM, predicting this East Coast Low. Note the Synoptic chart, 500Hpa Temperature and Humidity forecast.  Robin notes the combination of high humidity and very low temperature at 500Hpa together with the troughs funnelling air.

More from Robin H: East coast lows generally have very cold upper level areas fed with moist humid air from tropical areas. The high centred further south than usual at this time of the year is feeding the very cold air over NSW and then the trough feeding moist warm air in is a classical recipe for trouble. Thus inspection of temperature at the 500 mb level and then relative humidity to confirm the ingredients for trouble is a simple procedure for a do-it-yourselfer.

ORCV Announces the Launch of its All New Weather Course for 2014.

When and Where?

 

  • Modules One (Fundamentals of Weather Terminology) and Two (Enclosed Waters) - Sunday 13 April, 2014. Registration at 8:30am
  • Module Three (Coastal - up to 3 days duration) - Monday 28 April, 2014.  Commencing at 6:15pm

The Bureau of Meteorology has made significant progress with it’s forecasting in recent times and now achieves remarkable accuracy, especially out to 3 days.

 

With easy to use graphics and continual improvements the Bureau is working towards achieving higher degrees of accuracy for up to seven days and this technology has changed the focus of sailors.

 

This new course concentrates on the practical facets of weather applied to sailing, designed to cover the terminology, conditions and weather forecasting resources that will allow sailors of all persuasions to plan their trip from an afternoon on the Bay, through to a trans-ocean passage such as a Melbourne to Vanuatu or Melbourne to Osaka race, and the return delivery passages.
 
Further Details can be found on the ORCV Weather Course Website Here.
