  • 6. Annual Review and Significant Events
    6. Annual Review and Significant Events January-April: wet in the tropics and WA, very hot in central to eastern Australia For northern Australia, the tropical wet season (October 2005 – April 2006) was the fifth wettest on record, with an average of 674 mm falling over the period. The monsoon trough was somewhat late in arriving over the Top End (mid-January as opposed to the average of late December), but once it had become established, widespread heavy rain featured for the next four months, except over the NT and Queensland in February. One particularly noteworthy event occurred towards the end of January when an intense low (central pressure near 990 hPa) on the monsoon trough, drifted slowly westward across the central NT generating large quantities of rain. A two-day deluge of 482 mm fell at Supplejack in the Tanami Desert (NT), resulting in major flooding over the Victoria River catchment. A large part of the central NT had its wettest January on record. Widespread areas of above average rain in WA were mainly due to the passages of several decaying tropical cyclones, and to a lesser extent southward incursions of tropical moisture interacting with mid-latitude systems. Severe tropical cyclone Clare crossed the Pilbara coast on 9t h January and then moved on a southerly track across the western fringes of WA as a rain depression. Significant flooding occurred around Lake Grace where 226 mm of rain fell in a 24-hour period from 12 t h to 13 t h January. Tropical cyclone Emma crossed the Pilbara coast on 28 th February and moved on a southerly track; very heavy rain fell in the headwaters of the Murchison River on 1s t March causing this river’s highest flood on record.

  • Characterizing the Hydrodynamics of Jurien Bay, Western Australia
    Characterizing the Hydrodynamics of Jurien Bay, Western Australia Kellie Holloway June 2006 Professor Charitha Pattiaratchi ------------------------------------------------------------------------------------- This dissertation is submitted in partial fulfillment of the requirements for the Bachelor of Engineering (Applied Ocean Science) ------------------------------------------------------------------------------------- Abstract Abstract Jurien Bay is a small town on the Central West Coast of Western Australia. With an expanding economy based on fishing, aquaculture and tourism and proximity to Perth, Jurien Bay is expected to grow rapidly over the coming years. Increasing anthropogenic pressure has the potential to compromise the currently pristine natural environment. The livelihood of the town and the economy relies on the quality of the marine environment in particular; hence it is important to understand the dynamics of the system. This study investigates the characteristics of circulation in Essex Lagoon, a deep basin to the south of the main Jurien Bay settlement. This area is a particularly important for investigation due to the future impact of the adjacent Ardross Estates development and the aquaculture zone located within Essex Lagoon. An Acoustic Doppler Current Profiler (ADCP) was deployed in summer 2006 to obtain profiles of current velocity and magnitude over three weeks in Essex Lagoon. This data complemented similar data collected during winter 2002 in Essex Lagoon and was used to carry out a seasonal comparison of currents, to characterize circulation patterns and to examine the potential for outside forcing such as atmospheric pressure systems and the Leeuwin Current to influence circulation. A distinct seasonality was found in the circulation characteristics between summer and winter and this was primarily influenced by seasonality in the wind field.

  • Tropical Cyclone Emma 26 February – 1 March 2006
    Tropical Cyclone Emma 26 February – 1 March 2006 Perth Tropical Cyclone Warning Centre Bureau of Meteorology A. Summary Emma was a monsoonal-type low reaching category 1 intensity before crossing the coast near Mardie on 28 February, then moving to the south southeast and eventually passing near Esperance late on 1 March. The main impact was rainfall, initially in the Karratha/Dampier region and then over inland areas. The heavy rain in the headwaters of the Murchison River caused the highest recorded flood along the river. More than 20 pastoral properties reported significant damage and heavy infrastructure losses combined with significant scouring of the Murchison floodplain. Floodwaters peaked at Kalbarri at about midnight on 15 March. Although the sandbar was washed away and riverside and low-lying parts of the town were flooded, a significant sandbagging exercise protected the town centre from inundation. B. Meteorological Description A low developed within an active monsoon trough in the vicinity of 12S 114E well to the north of NW Cape on 25 February. Convection remained unorganised and pulsed diurnally peaking around 0000 UTC 26 February for example. Although day-time visible images showed increasing rotation, convection remained unorganised overnight. Quickscat at 2245 UTC 26 February showed the centre further to the south southwest than the previous day possibly suggesting some re-organising of the LLCC. Convection became more sustained to the south and east but quite removed from the centre. Quickscat at 0952 UTC 27 February indicated gales well to the south and east but marginally less than 50 per cent surrounding the centre and well removed.

  • CYCLONE EMMA - HELP from VOLUNTEERS and AGENCIES Statement by Minister for Police and Emergency Services MR J.B
    Extract from Hansard [ASSEMBLY - Tuesday, 28 March 2006] p776c-777a Mr John D'Orazio CYCLONE EMMA - HELP FROM VOLUNTEERS AND AGENCIES Statement by Minister for Police and Emergency Services MR J.B. D’ORAZIO (Ballajura - Minister for Police and Emergency Services) [2.12 pm]: In Western Australia, 2006 has been a busy year when it comes to cyclones and the flooding associated with them. First there was tropical cyclone Clare, quickly followed by tropical cyclone Daryl, and then at the start of this month tropical cyclone Emma. While we have been fortunate not to experience the likes of tropical cyclone Larry that has devastated parts of Queensland, Western Australian communities have had their share of heartbreak. I acknowledge the work of a number of agencies and volunteers involved with the aftermath of tropical cyclone Emma. Tropical cyclone Emma dumped record rains on a number of towns in the Pilbara and Midwest regions, which resulted in the largest volume of river water seen in the Murchison basin in 45 years. It was recorded that the river had swollen to over 20-kilometres wide in parts normally only 500-metres wide. Eleven stations received early warning, advice and assistance. Unfortunately, the homesteads of four of these stations were inundated with water. All of the other stations reported water encroaching into outbuildings such as shearing sheds and living quarters. The township of Kalbarri fared better after a coordinated effort, and plenty of hard work resulted in minimal damage. Credit must be given to all involved. A large number of volunteers, local government and government agencies - WA Police, the Water Corporation, Western Power, Main Roads WA, the Department of Conservation and Land Management, the Department of Water and the Flood Warning Centre - along with community members and business, worked together on the preparations at Kalbarri.

  • Annual Pastoral Land Condition Report, Western Australia 2005–06
    _____________________________________________________________________________ Western Australia Annual Pastoral Land Condition Report 2005/2006 A report prepared for the Pastoral Lands Board of Western Australia by the Department of Agriculture and Food December 2006 _____________________________________________________________________________ Annual Report to the Pastoral Land Board 2005/06 i _____________________________________________________________________________ EXECUTIVE SUMMARY The following 2005/06 Annual Report to the Western Australian Pastoral Lands Board presents an assessment of overall land condition on pastoral properties throughout the Rangelands of Western Australia. The Western Australian Rangelands pastoral estate consists of 466 Stations covering approximately 910 000km2. This equates to 42% of the States Rangelands. The total number of pastoral leases has continued to decline from the previous reporting period and there are currently 478 stations (525 Leases). The Rangelands are made up of a diverse range of climates from the semi arid tropics in the north to the arid south. Topography and rainfall varies significantly. This diversity has led the demand for diversification of use for the rangelands that are not based on traditional pastoralism. At the recent ‘Gascoyne Muster – The Next generation’ the Minister for Planning and Infrastructure flagged the intention to address the issue of diversification of use on pastoral leases as the next key topic following rolling tenure. The northern rangelands remain predominantly cattle focussed on the export market. The southern rangelands have seen a continuing trend over the past 20 years of an expansion of the cattle industry at the expense of the sheep industry. The Western Australian Rangeland Monitoring system is designed to report at the regional or district scale. 2005/06 assessments indicate that sites in the Kimberly showed no significant change in perennial grass frequency over the last three years.
