Record Early-Season Heat In Northern Australia ( Source: Weatherzone ) Yesterday was exceptionally hot in northern Australia, with a weather station in WA registering the Southern Hemisphere's first 45ºC of the season. A stagnant pool of hot air has been sitting over parts of the NT, QLD and northern WA this week, causing a Severe to Extreme heatwave in parts of each state and territory.  On Wednesday morning, Darwin registered its highest October minimum temperature (29.0ºC) in 137 years of records. This was followed by minimums of 28.9ºC on Thursday and 28.8ºC on Friday, making it Darwin's hottest trio of mornings on record outside the wet season. Then on Thursday, temperatures in some areas soared to levels never before seen during October. In WA, Wyndham's 45.1°C on Thursday afternoon was the town's highest October temperature on record, and Australia's highest October temperature since 2014. According to Maximiliano Herrera, a climatologist who monitors global temperature extremes, this was also the Southern Hemisphere's first 45°C so far this season. WA's Kununurra also broke its October record on Thursday afternoon, reaching a top of 44.0ºC to oust the previous record of 43.9ºC from 2002. Over the border in the NT, a weather station at Victoria River Downs reached 44.9ºC on Thursday afternoon. This was the site's highest October temperature on record for the second day in a row. It was also the second highest temperature ever reliably recorded in the NT during October. The heatwave will gradually break down over much of northern Australia in the coming days, as cooler air, showers and thunderstorms push in from the northeast. |

Last night saw some classic 'build up' action across the Top End. This noisy and sparky mutha rolled through in the early hours of the morning. And as usual with these storms, very patchy, had to be lucky to be underneath one and score some rain.   I scored exacty 0....not a fucken drop !  |

Stormy out in the rural area this afternoon, unlikely it will push in against the coastal sea breeze.  |

Bureau of Meteorology We're not magicians, but if you're lucky enough to live in northern Australia, we know a way to make your shadow disappear (well almost!) As the Earth zips around the Sun, one side is always in daylight, and there's always a point on the Earth's surface where the Sun is directly overhead. This is known as the subsolar point - when the Sun's rays are perpendicular, or exactly 90⁰, to the ground. At this point in time the shadows of trees, buildings, people, and in fact any object are at their shortest. But why does this only affect the tropical regions of the world? Well as the Earth tilts, it also moves the subsolar point on the Earth's surface. This varies its position with the seasons, reaching north-south as far as the Tropic of Cancer (~23.5⁰N) in the north and the Tropic of Capricorn (~23.5⁰S) in the south. In fact, tropical regions get two days per year where the sun is overhead, although you'll have a better chance at casting a shadow in the generally sunnier conditions before Christmas. ☀️Darwin - 26 October 2021 (1230) & 16 February 2022 (1300) ☀️Cairns - 09 November 2021 (1200) & 02 February 2022 (1230) ☀️Townsville - 18 November 2021 (1157) 24 January 2022 (1224) Those outside of the tropics, in southern Australia will experience their shortest shadows during summer solstice on 21 December. Darwin 12.30pm today   |

Australia's Tropical Cyclone Season Is About To Begin ( Source: Weatherzone ) Australia's tropical cyclone season starts next week, so what is in store for Australia this season? The official tropical cyclone season runs for six months, from November through to April. This is the time of year when conditions are most suitable for cyclones to develop near northern Australia. Tropical cyclones are intense low-pressure systems that draw their energy from warm tropical waters, typically when the sea surface temperature is above 26.5°C. Once above this threshold, each degree of warming provides additional energy for developing tropical cyclones. Warmer oceans around Australia's northern tropics can be a sign of an active tropical cyclone season. This relationship can help forecasters predict how active an upcoming season will be. The image below shows abnormally warm Sea Surface Temperatures (SST’s) near Australia's northern tropics this week.  The warm SST's in the image above are the result of a negative phase of the Indian Ocean Dipole (IOD) and a developing La Niña in the Pacific Ocean. Both of these climate drives could influence the upcoming tropical cyclone season. The negative IOD is on its way out and should return to a neutral phase in November. However, even in a weakening state, the negative IOD can still help enhance early-season tropical cyclone activity. During the last six negative IOD events, the average first coastal crossing in Australia was around mid-November. This is earlier that the average first coastal crossing in Australia in the absence of a negative IOD, which is usually around early January. While the IOD is breaking down, La Niña is looking increasingly likely between this November and at least February next year, which will warm the waters across northern Australia further. During La Niña years, the first tropical cyclone coastal crossing typically occurs around mid-to-late December, which is about half a month earlier than usual. The combination of La Niña and favorable ocean temperatures near northern Australia are forecast to bring an increase in tropical cyclone and deep tropical low activity. In an average season, we usually see around 9 to 11 tropical cyclones in the Australian region. Weatherzone's modelling predicts that there will be about 12-13 cyclones in the region this season. The image below breaks down this forecast for each region in Australia’s area of responsibility.  Is climate change affecting the number of tropical cyclones? Australia's tropical cyclone seasons have a lot of year-to-year variability. However, in the last three-to-five decades, we have seen a reduction in the overall number of tropical cyclones in the Australian region in response to climate change. Global warming is affecting temperature, wind and pressure patterns across the planet, which is altering the environments in which tropical cyclones develop. Despite warming oceans, which are providing more energy for cyclone development, we have also seen an increase in tropical wind shear (winds that change speed and direction with height) in recent decades, which has hindered the development of tropical lows and cyclones. Tropical cyclones thrive when wind shear is weak. When there is too much wind shear, the top of the cyclone can be blown hundreds of kilometers downstream, ripping the cyclone apart. While overall tropical cyclone activity is decreasing, we are seeing a higher proportion of more intense tropical cyclones.  This season, the background effect of climate change should be compensated by favorable warm ocean temperatures and La Niña, leading to a near to slightly above average number of tropical cyclones this season. It only take one cyclone to cause damage in your area, so make sure you stay up to date with the latest cyclone forecasts and warnings if you live in northern Australia. |

Sweltering Build-Up Nights For The Top End ( Source: Weatherzone ) As the last day of October approaches, Darwin's overnight temperatures for the month are still breaking records. After the warmest October night on record was measured on the 20th, the average minima across the month now looks set to break a similar record. For October 2021 so far, Darwin nights have averaged a sticky 26.6°C, nearly 2°C above the long-term average. This is a huge margin for the tropics where annual temperature variability is very small. Average monthly temperatures, for example, vary only 6 degrees across the entire year, from 19°C in July to 25°C in November and December. With only one night to go, October minima are set to be the warmest in the 80 year record for the Darwin airport site. The next warmest was October, 1987. Maxima have also been high, currently sitting at 34.4 degrees averaged over the month, just over 1 degree above the long-term average. Growing up in the nineties in the northern capital, I remember long strings of days of 33°C, and a look at records from the time bears this out. A string of more than 2 days together over 35°C degrees was rare in the 90’s, occurring just 5 times over the decade. In the last decade, it's happened 12 times, including one stretch of 7 consecutive days in 2019. October, and also November, are typically sticky and awful as moisture builds ahead of the wet season. There's a reason that if you're going to "go troppo," it's during these months. But the temperatures in recent years are unusual, even for seasoned locals. It's not just Darwin either. Batchelor, down the track in Litchfield Park, and Jabiru, near Kakadu, also have minimum temperatures sitting over a degree above average for this month--the warmest since records began for those centres in 1994 and 1971 respectively. As October merges into November, sticky build-up conditions are set to continue. Showers and thunderstorms will become likely on Tuesday and Wednesday, bringing intermittent cooling, but each day this week is still forecast at 35°C or higher.  |

An absolute cracker of an early morning storm passing over the City atm. A classic Gulf Line travelling East accross the Top End, and impacting my suburb ( Leanyer Heights ) just before 5.00am   |

Another Gulf Line came through the coastal suburbs this morning, dropping a quickfire 7.3mm in my gauge. Seems like the season has changed, with increasing showers and storms in the forecast. Once the rain cleared up, that bastard sun came out and peaked above 35c, so a steamy hot humid day.   Next 7 days forecast.  |
