Welcome to Weather On The Go.
欢迎来到“天气不停播”。
Today we're looking at heatwaves.
今天我们把目光聚焦在热浪之上。
Heatwaves may not sound as dangerous as fires or floods, but they're actually Australia's deadliest natural disaster.
光就听上去的话，热浪似乎没有火灾和洪灾那么地吓人，但它实际上却是澳大利亚最具杀伤力的自然灾害。
In the Black Saturday fires of 2009, over 170 people died.
在2009年的黑色星期六火灾中，超过170人失去了生命。
But it's less well-known that nearly 500 people died during the heatwave that happened at the same time.
但鲜为人知的是，有近500人在同时间的热浪中丧生。
Heatwaves arise when there are a number of days in a row where the temperature is unusually hot.
热浪通常会在持续多日的异常高温天气中出现。
Both daytime and night-time temperatures are important for heatwaves, because if it's hot overnight, there's no chance to cool down.
白天和夜晚的温度对热浪的形成都有着重要的影响，这是由于持续的高温会让天气没有机会在夜晚得到降温。
A heatwave also depends upon where you are.
热浪的形成还受地理位置的影响。
A heatwave in Tasmania, where it's generally colder, will not technically be as hot as one in Queensland.
由于常年处于相对的低温气候之中，严格来说，塔斯马尼亚岛的热浪并不会像昆士兰那么热。
But it'll still feel very warm to those who live there.
不过这样的气温对于那些住在当地的人来说也并不算低了。
Heatwaves are particularly dangerous for those in the community who are already vulnerable, like the elderly, the sick and the very young.
对一个社区中诸如老人、病人、儿童一类的弱势群体来说，热浪是极具危险性的。
So it's important to look out for your neighbors and elderly relatives.
所以对邻居和长辈的关心就显得十分地重要。
And don't forget your pets.
当然也别把你的宠物给忘了。
During extreme heat, make sure they have access to plenty of water and shaded areas.
在炎热天气里，确保他们有充足的水和乘凉的地方。
The Bureau of Meteorology sends out warnings when heatwaves are on the way and it's also reported in the media.
在热浪来袭时，气象局会发出预警，媒体也会对此进行报道。
Or you can find them yourself on the Bureau of Meteorology website.
你也可以自己在气象局的网站上找到相关信息。
So when it's hot out there, try to stay in cool places, avoid spending too much time out in the sun and take it easy when you do have to go out.
所以，当外面实在是酷热难耐的时候，尽量呆在凉爽的地方，避免在阳光下久留，如果不得不外出也要保持轻松的心情。
Wear a hat, drink lots of water and be sure to check on those around you.
戴上帽子，多喝水，同时也别忘了留意一下周围的人。
