Monthly Weather Review Western Australia March 2009 Monthly Weather Review Western Australia March 2009

The Monthly Weather Review - Western Australia is produced twelve times each year by the Australian Bureau of Meteorology's Western Australia Climate Services Centre. It is intended to provide a concise but informative overview of the temperatures, rainfall and significant weather events in Western Australia for the month. To keep the Monthly Weather Review as timely as possible, much of the information is based on electronic reports. Although every effort is made to ensure the accuracy of these reports, the results can be considered only preliminary until complete quality control procedures have been carried out. Major discrepancies will be noted in later issues. We are keen to ensure that the Monthly Weather Review is appropriate to the needs of its readers. If you have any comments or suggestions, please do not hesitate to contact us: By mail Western Australia Climate Services Centre Bureau of Meteorology PO Box 1370 WEST PERTH WA 6872 AUSTRALIA By telephone (08) 9263 2222 By email [email protected] You may also wish to visit the Bureau's home page, http://www.bom.gov.au. Units of measurement Except where noted, temperature is given in degrees Celsius (°C), rainfall in millimetres (mm), and wind speed in kilometres per hour (km/h). Observation times and periods Each station in Western Australia makes its main observation for the day at 9 am local time. At this time, the precipitation over the past 24 hours is determined, and maximum and minimum thermometers are also read and reset. In this publication, the following conventions are used for assigning dates to the observations made: Maximum temperatures are for the 24 hours from 9 am on the date mentioned. They normally occur in the afternoon of that day. Minimum temperatures are for the 24 hours to 9 am on the date mentioned. They normally occur in the early morning of that day. Daily rainfall is for the 24 hours to 9 am on the date mentioned. This means a significant fraction of the rain may have occurred on the previous calendar day. Monthly rainfall is for the period from 9 am on the last day of the previous month to 9 am on the last day of this month. Maximum daily wind gusts are in the 24 hours from midnight to midnight. Climatological values The climatological averages shown in the text and tables are generally long-term means based on observations from all available years of record, which vary widely from site to site. They are not shown for sites with less than 30 years of record, as they cannot then be calculated reliably. Climatological extremes are generally taken from available observations from all available years of record. The number of years can vary substantially from site to site.

Overview • Monthly rainfall near average. Extremes in March 2009 • Mean daily maximum temperature near average. • Mean daily minimum temperature near average. Hottest day March 2009 in Western Australia saw above average (Highest daily maximum temperature) rainfall in the east Pilbara, east Gascoyne, northern 44.5 °C at Onslow on the 28th Goldfields and western Interior mostly due to heavy Warmest days on average rainfall from a tropical low at the beginning of the (Highest mean daily maximum temperature) month that caused flooding in these regions. In 39.5 °C at Emu Creek Station contrast, the north and east Kimberley, west Pilbara Coolest days on average and parts of the central and west Gascoyne received (Lowest mean daily maximum temperature) much lower than normal rainfall for March. Two 22.0 °C at Albany tropical cyclones formed in the WA region, however Coldest day neither affected the WA coast. (Lowest daily maximum temperature) Averaged over WA as a whole, both mean daily 15.0 °C at Mount Barker on the 31st maximum and minimum temperatures for March Coldest night 2009 were near average. In terms of mean maximum (Lowest daily minimum temperature) temperatures, most southern and central parts of 2.5 °C at Wandering on the 3rd WA saw near average conditions, whilst much of the Coolest nights on average Kimberley and northern Interior experienced higher (Lowest mean daily minimum temperature) than normal mean maxima. Mean minima were close 10.1 °C at Jarrahwood to average for much of the state although some Warmest nights on average parts of western WA saw below average minima, and (Highest mean daily minimum temperature) parts of the northern Interior and southern 27.3 °C at Troughton Island Kimberley recorded above average minima. (On the WA mainland) 25.6 °C at Broome Airport Warmest night (Highest daily minimum temperature) 29.8 °C at Wittenoom on the 16th Wettest overall (Highest total rainfall) 234.0 mm at Bonney Downs Wettest day (Highest daily rainfall) 137.0 mm at Marble Bar (DoW) on the 1st Highest wind gust 104 km/h at Wyndham Aero on the 3rd

Maximum temperatures Anomalies of mean daily maximum temperature in March 2009 The mean daily maximum temperature for March 2009 for WA was 0.5 °C above average, which falls into the near average category. Although central parts of the state saw generally close to normal temperatures during March, most northern parts of WA saw above average mean maxima with the far southeast Kimberley and northeast Interior up to 4 °C warmer than normal, and the Exmouth area up to 3 °C warmer than normal. South coast districts were generally below average with eastern parts of the Eucla up to 2 °C cooler than the long term mean. The hottest day was 44.5 °C at Onslow on the 28th, followed by 43.7 °C at Roebourne Aero also on the 28th. The warmest days on average were 39.5 °C at Emu Creek Station, followed by 39.3 °C at Balgo Hills. The coolest day was 15.0 °C at Mount Barker on the 31st, followed by 16.0 °C at Rocky Gully also on the 31st. Decile rank of mean daily maximum temperature in March 2009 The coolest days on average were 22.0 °C at Albany, followed by 22.4 °C at Cape Leeuwin.

Minimum temperatures Anomalies of mean daily minimum temperature in March 2009 Averaged over WA as a whole, the mean daily minimum temperature for WA for March 2009 was 0.4 °C lower than the long term mean, but was in the near average range. Parts of the western half of the state were up to 2 °C cooler than normal, including in the Gascoyne and Lower West, while in the east Pilbara, south Kimberley and northern Interior, overnight temperatures were up to 2 °C warmer than normal. The coldest night was 2.5 °C at Wandering on the 3rd, followed by 3.0 °C at Collie East also on the 3rd. The coolest nights on average were 10.1 °C at Jarrahwood, followed by 10.4 °C at Bridgetown. The warmest nights on average were 27.3 °C at Troughton Island whilst on the mainland Broome Airport recorded 25.6 °C. The warmest night was 29.8 °C at Wittenoom on the 16th.

Rainfall

Averaged across WA as a whole, March 2009 rainfall Total rainfall in March 2009 was close to average. Parts of the east Pilbara, east Gascoyne, northern Goldfields and western Interior saw above average rainfall, mostly due to heavy falls from a tropical low at the beginning of the month that moved through the east Pilbara and caused flooding in these regions. The weakened low also brought rainfall to the Eucla and southeast Interior, with totals in these regions in the above average range for March. In contrast, the north and east Kimberley, west Pilbara and parts of the central and west Gascoyne received much lower than normal rainfall for March as no other tropical low pressure systems affected WA during the month. Two tropical cyclones formed in the WA region, however neither affected the WA coast. The wettest overall was 234.0 mm at Bonney Downs, followed by 168.2 mm at Marble Bar. The wettest single day 137.0 mm at Marble Bar (DoW) and 135.0 mm at Marillana, both on the 1st. Decile rank of total rainfall in March 2009

Daily and total rainfall for March 2009 Total is the total precipitation for March 2009; a missing total indicates there is concern about the quality of some of the daily values. Avg is the long-term average total precipitation for March. Decile is the decile rank of total precipitation for March 2009 in the climate record of other March totals; “L” indicates this is the lowest on record, and “H” it is the highest on record. Long-term average and decile rank are only shown if there are sufficient years of climate record available. Reports of zero precipitation are shown as “· ”. When a reading was accumulated over more than one day, “»” is shown on the days that are part of the accumulation.
