Radar, an electromagnetic sensor used for detecting, locating, tracking, and recognizing objects of various kinds at considerable distances. It operates by transmitting electromagnetic energy toward objects, commonly referred to as targets, and observing the echoes returned from them.

Weather radar mainly means detecting precipitation systems and is one of the main tools for monitoring and warning of strong convective weather (hail, high winds, tornadoes and flash floods).]]> 2023-06-09 02:54:04 UTC https://padlet.com/30langsiyao/i0gvsj51go1vprwp/wish/2618870862 它的材料 It’s materials 30huangzihan https://padlet.com/30langsiyao/i0gvsj51go1vprwp/wish/2618906285 雷达结构常用的黑色金属材料包括碳素钢、合金结构钢、轴承钢等，用来做结构受力件等。在雷达行业中，由于铝和铝合金具有密度小、比强度高等优点，为了实现雷达设备的轻量化，铝及合金在雷达结构中得到了广泛的应用。因为铝合金有优良的导电性能，所以铝合金也用于雷达的馈线结构中，如波导、功分器、电桥等结构。
The ferrous metal materials commonly used in radar structures include carbon steel, alloy structural steel, bearing steel, etc., which are used as structural force parts. In the radar industry, aluminum and alloy have been widely used in radar structure because of the advantages of low density and high specific strength, in order to achieve the weight reduction of radar equipment. Because aluminum alloy has excellent conductivity, aluminum alloy is also used in the feeder structure of radar, such as waveguides, power dividers, bridges and other structures.]]> 2023-06-09 03:28:22 UTC https://padlet.com/30langsiyao/i0gvsj51go1vprwp/wish/2618906285 30wangxier https://padlet.com/30langsiyao/i0gvsj51go1vprwp/wish/2618908117 天气雷达对于提供准确的实时和及时的每小时“即时”天气报告至关重要。这项技术可以成为气象学家准确预报降水到来的最佳工具。也许更重要的是能够预测即将到来的降水的强度和严重程度，并突出显示对生命和财产造成危险的可能性是高还是低。
雷达数据也可以被引入预报模型（例如 The Weather Company 的 IBM 全球高分辨率大气预报 (IBM GRAF) 模型），这有助于更好地初始化生成更好的短期预报所需的数据，通常在36小时。
对于新闻台或公用事业公司，雷达是其预测策略的支柱。气象学家使用天气雷达帮助观众了解情况，以便他们知道如何为恶劣天气做准备并决定是否应该撤离某个区域。公用事业公司使用雷达数据来了解何时以及如何让工作人员为潜在的停电做好准备。
Weather radar is crucial to providing accurate real time and timely hourly “now cast” weather reports. This technology can be the best tool for meteorologists to accurately forecast the arrival of precipitation. Perhaps more important is the ability to forecast the intensity and severity of the approaching precipitation and highlight whether there’s a high or low probability of danger to life and property.
The radar data can also be ingested into forecast models (like the IBM Global High-Resolution Atmospheric Forecasting (IBM GRAF) model from The Weather Company), which aids in much better initialization of data needed to generate better short-range forecasts, generally within 36 hours.
For news stations or utility companies, radar is the backbone of their forecast strategy. Meteorologists use weather radar to help keep viewers informed so they know how to prepare for severe weather and decide if they should evacuate an area. Utility companies use radar data to know when and how to prepare crews for potential outages.

How it works? 30huangzihan https://padlet.com/30langsiyao/i0gvsj51go1vprwp/wish/2618909345 气象雷达利用固态或电子管发射器向空中发送能量脉冲（也称为雷达波束）以检测降水。这种聚焦波束从天线（也称为雷达天线）向外辐射。如果雷达波束从雨水或冰雹等降水中反弹，波束将返回天气盘，在那里数据被处理成各种参数。这使气象学家能够分析和解释距离雷达数十英里的天气类型。
天气预报员通过返回天气雷达站点的脉冲的强度和速度来确定到即将到来的风暴的距离和降水量。还可以进行降水类型，运动，湍流和更多有用的确定，例如识别龙卷风将抛向空中的碎片（称为碎片球）。
Weather radar utilizes either a solid-state or tube transmitter to send energy pulses (also known as radar beams) into the air to detect precipitation. This focused beam radiates outward from an antenna (also known as a radar dish). If the radar beam bounces off precipitation such as rain or hail, the beam will return to the weather disk, where the data is processed into various parameters. This enables a meteorologist to analyze and interpret the type of weather occurring dozens of miles away from the radar.
Weather forecasters determine the distance to an oncoming storm and the amount of precipitation by the strength and speed of the pulse returning to the weather radar site. Precipitation type, motion, turbulence and many more useful determinations can also be made, such as recognizing the debris that a tornado would throw into the air (known as a debris ball).

Also,I want to learn about how the radar work(how does it  forecast the weather)and in the past when it doesn’t have radar how do people do with the typhoon and the flood and etc.
我选择天气预报中的雷达这个主题是因为它的其中有人类的智慧，还运用到了能量，我觉得很贴合这个探究单元。而且，我还想要知道雷达是怎么预测天气的和以前当雷达还没有被发明出来时人们是怎么应对向台风、洪水等极端天气的。雷达还能防止很多人的伤亡（因为它能够预测天气）。]]> 2023-06-09 09:35:56 UTC https://padlet.com/30langsiyao/i0gvsj51go1vprwp/wish/2619199298 Shell王熙尔 30wangxier https://padlet.com/30langsiyao/i0gvsj51go1vprwp/wish/2619313531 The reason of why I chose weather forecast in radar is that I wonder how it predicts weather.In forth grade,I completed a unit of inquiry that is about extreme weather，and it made me to be curious about weather forecasting. Weather radar is a topic connected to energy ,which is what we studied in UOI classes.I also want to gain knowledge by researching the timeline, impact of radar and what energy it uses.
我选择天气预报中的雷达是因为我很好奇它是怎么预测天气的。在四年级的时候，我完成了一个关于极端天气的探究单元，它让我有了探究关于天气预报的感觉。天气预报中的雷达和我们探究单元所学的能量有关。我还想通过本次总结性评估了解到关于天气雷达的时间线，对人们生活的影响，以及它所用的能量。]]> 2023-06-09 12:46:39 UTC https://padlet.com/30langsiyao/i0gvsj51go1vprwp/wish/2619313531 Elsa黄子涵 30huangzihan https://padlet.com/30langsiyao/i0gvsj51go1vprwp/wish/2619788984 I chose this topic because in real life, weather radar has helped people a lot and is the crystallization of human intelligence. For example, in real life, you will look at the weather forecast every day so that you can determine what to wear and what to bring today or in the next few days. Radar can calculate the nearest weather through satellite monitoring so that people can be prepared. Moreover, the radar in the weather forecast also reflects the theme energy in our UOI unit.
我选择这个主题是因为在实际生活中，天气雷达帮了人们很大的忙，是人类智慧的结晶。比如在实际生活中，每天你都会看一下天气预报这样才能确定今天或最近几天要穿什么衣服，带什么东西。雷达就可以通过卫星的监测计算出最近的天气，以便人们做好准备。并且，天气预报中的雷达也体现了我们这个探究单元中的能量与能源。]]> 2023-06-10 09:45:41 UTC https://padlet.com/30langsiyao/i0gvsj51go1vprwp/wish/2619788984 Erica郭天睿 30guotianrui https://padlet.com/30langsiyao/i0gvsj51go1vprwp/wish/2620588349 I chose this theme because radar in real-life weather forecasting helps us a lot, it can predict the weather and prepare people before some extreme weather comes. And it fits the key word "energy" in this unit of inquiry. Most importantly, I think it is the result of human ingenuity, so I want to explore its "past and present lives" and study its mysteries.
我选择这个主题是因为在现实生活中天气预报中的雷达帮了我们很多忙，它可以预测天气，让人们在一些极端天气来临之前有所准备。而且很贴合这个探究单元中的“能量”这个重点词语。最重要的是，我认为它是人类智慧的结晶，所以想去探究它的“前世今生”，并研究它的奥秘。]]> 2023-06-12 02:45:24 UTC https://padlet.com/30langsiyao/i0gvsj51go1vprwp/wish/2620588349 30huangzihan https://padlet.com/30langsiyao/i0gvsj51go1vprwp/wish/2620597562 2023-06-12 02:53:29 UTC https://padlet.com/30langsiyao/i0gvsj51go1vprwp/wish/2620597562 30langsiyao https://padlet.com/30langsiyao/i0gvsj51go1vprwp/wish/2622947160 2023-06-14 03:19:34 UTC https://padlet.com/30langsiyao/i0gvsj51go1vprwp/wish/2622947160 30langsiyao https://padlet.com/30langsiyao/i0gvsj51go1vprwp/wish/2622947791 2023-06-14 03:20:13 UTC https://padlet.com/30langsiyao/i0gvsj51go1vprwp/wish/2622947791 30langsiyao https://padlet.com/30langsiyao/i0gvsj51go1vprwp/wish/2622949078 2023-06-14 03:20:32 UTC https://padlet.com/30langsiyao/i0gvsj51go1vprwp/wish/2622949078 30langsiyao https://padlet.com/30langsiyao/i0gvsj51go1vprwp/wish/2622953034 2023-06-14 03:24:30 UTC https://padlet.com/30langsiyao/i0gvsj51go1vprwp/wish/2622953034 30langsiyao https://padlet.com/30langsiyao/i0gvsj51go1vprwp/wish/2622953236 2023-06-14 03:24:42 UTC https://padlet.com/30langsiyao/i0gvsj51go1vprwp/wish/2622953236 30langsiyao https://padlet.com/30langsiyao/i0gvsj51go1vprwp/wish/2623057649 2023-06-14 05:26:19 UTC https://padlet.com/30langsiyao/i0gvsj51go1vprwp/wish/2623057649 30guotianrui https://padlet.com/30langsiyao/i0gvsj51go1vprwp/wish/2624233189 2023-06-15 06:15:14 UTC https://padlet.com/30langsiyao/i0gvsj51go1vprwp/wish/2624233189 https://padlet.com/30langsiyao/i0gvsj51go1vprwp/wish/2624998465 特别棒！条理清晰，内容饱满！
