Spider season in Australia linked with extreme changes of temperature




A spider season – the springtime in Australia, is bringing really strong changes of temperature across the continent.

On the one hand, parts of Southern Hemisphere has experienced with one of the best winters for last 20 years /https://mkweather.com/2020/08/12/patagonia-with-one-of-the-cruelest-winter-for-last-20-years/; https://mkweather.com/2020/08/12/confirmed-tasmania-with-the-coldest-temperature-ever-142c-6f/; https://mkweather.com/2020/08/24/cruel-winter-in-patagonia-continue-massive-losses-of-sheep-100-000-killed-in-patagonia-because-of-intense-snowstorms/; https://mkweather.com/2020/08/21/snowing-in-the-northernmost-latitude-in-australia-for-last-15-winters-since-2005-and-the-coldest-day-of-winter-2020-in-new-south-wales-expected-at-the-weekend-new-zealand-with-heavy-rain-185-mm-96/; https://mkweather.com/2020/08/13/brasil-is-waiting-a-historic-coldwave-temperatures-will-drop-30c-below-average-around-20-august-2020/; https://mkweather.com/2020/08/04/antarctic-blast-hit-australia-snowing-in-melbourne-and-hobart-105c-13f-and-the-coldest-4-days-for-last-24-years//, on the other hand, ITCZ (Intertropical Convergence Zone is shifting southward in the region /https://mkweather.com/2020/09/28/itcz-is-shifting-southward-floods-in-indonesia-java-kalimantan-sulawesi-west-papua-has-started-cause-problems-wet-mjo-is-bringing-severe-storms-in-vietnam-338-mm-24-hours-and-myanmar// and dry tropical air is shifting from Indonesia back to Australia.

Already in September 2020 we have informed about extreme changes of weather in Australia and quick shifts from hot tropical weather in northern regions to last Antarctic blobs in southern regions has occurred too during last days. Heatwaves alternated with severe cold fronts with storms, wind and subsequent coldwaves are expected in October, too.

Before a big Australian heatwaves in the middle of September 2020 /https://mkweather.com/2020/09/16/australia-405c-heatwaves-has-come-extremely-early-adelaide-30c-melbourne-25c-next-days// has occurred severe blizzard conditions in Southeast. Heatwave brought temperatures over +40°C in northern areas (10°C above average – very early start of extreme heatwaves), in Adelaide was measured almost +30°C, Melbourne +26°C /https://mkweather.com/2020/09/22/adelaide-296c-85-3f-melbourne-263c-79-3f-at-the-weekend-north-australia-408c-105-4f-after-powerful-cold-front-blizzard-in-australian-alps// and then, during 3rd September decade arrived next coldwave, with next significant snowy conditions in Southeast – it was snowing in 200 MASL! /Australia coldwave 1/. This coldwave hit New Zealand a few days later /https://mkweather.com/2020/09/28/new-zealand-after-windy-an-rainy-weekend-with-snowing-in-dunedin-in-australia-a-big-temperature-extremes-are-expected-during-the-weekend//.

After Antarctic blob, next powerful heatwave has appeared and Adelaide has measured +30,9°C and Melbourne +26,0°C, on Friday, 2. October, but next powerful cold blast is coming /Australia coldwave 2/. After long coldwave, next strong temperature fluctuations could appear during the second October decade, but changes won´t be so severe such as last and next weeks.

It appears that spiders in Australia have more turbulent season. Soon, extremely hot air floods the whole territory of Australia and starts a dangerous wildfires and bushfires, which were in last season (summer 2019/2020) in Australia historic.
