风暴追逐者焦点问题风暴追逐者如何研究天气?
Follow That Storm A storm is brewing and it's a monster! It may be a thunderstorm, hurricane, or tornado. These storms are dangerous. When severe weather heads in your direction, your family probably takes shelter. You may even leave town—anything to get out of the storm's path. But a few people go toward or even into a big storm. Sometimes they are lucky to survive. Who are they? Storm chasers.
一场暴风雨正在酝酿,它是一场怪物!可能是雷暴、飓风或龙卷风。 这些风暴很危险。 当恶劣天气朝你的方向袭来时,你的家人可能会找地方躲避。 你甚至可以离开城镇——为了避开风暴的路径。 但也有少数人走向甚至陷入大风暴。 有时他们很幸运能活下来。 他们是谁?风暴追逐者。
What Are Storm Chasers? Storm chasers are people who track extreme storms. Many storm chasers are weather scientists called meteorologists. Getting close to storms helps them collect more information than they could get from far away. How fast is a tornado moving? Will a hurricane hit the coast? Questions like these are hard to answer without getting close to a storm. Storm chasers follow storms to help keep people safe. They gather data, take photos, and shoot videos to convince people to prepare for the storm. Do You Know? Benjamin Franklin may have been the first storm chaser. In 1752, he flew a kite during a thunderstorm to study electricity.
什么是风暴追逐者?风暴追逐者是追踪极端风暴的人。 许多风暴追逐者都是气象学家。 与远离风暴相比,接近风暴可以帮助他们收集更多的信息。 龙卷风移动的速度有多快? 飓风会袭击海岸吗? 在没有接近风暴的情况下,这样的问题很难回答。 风暴追逐者跟随风暴来帮助保护人们的安全。 他们收集数据,拍摄照片,拍摄视频,说服人们为风暴做好准备。 你知道吗?本杰明·富兰克林可能是第一个风暴追逐者。 1752年,为了研究电学,他在雷雨天放风筝。
Finding the Storm Storm chasers have to find a storm before they can chase it. They watch for weather patterns that usually lead to dangerous storms. By looking at wind direction storm chasers can tell which way the wind is blowing. Wind speed shows how fast the wind is blowing. Quick changes in air temperature and air pressure can mean a storm is brewing. Humidity, the amount of moisture in the air, is usually high near big storms. By looking at all these features of weather, storm chasers can predict when and where a storm might form. Technology Some digital weather sensors collect all these measurements at once.
寻找风暴追逐者必须在追逐风暴之前找到风暴。 他们观察通常会导致危险风暴的天气模式。 通过观察风向,风暴追逐者可以知道风是从哪个方向吹来的。 风速表示风吹得有多快。 空气温度和气压的快速变化可能意味着风暴正在酝酿。 湿度,即空气中的水分含量,在大风暴附近通常很高。 通过观察天气的所有这些特征,风暴追逐者可以预测风暴可能形成的时间和地点。 一些数字天气传感器一次性收集所有这些测量数据。
Storm chasers also scan weather maps, satellite pictures, and radar images for clues that bad weather is coming. Weather Map Storm reports can show cloud and wind patterns that led to big storms in the past. If the same conditions happen again, a storm may be coming. Satellite Picture Satellites high above Earth take pictures of clouds. Storm chasers look at the shape and movement of the clouds to predict extreme weather. A hurricane looks like a spiral from space. Radar Image Radar devices send out signals that bounce off raindrops and water droplets inside clouds. Computers turn the data into colorful cloud maps that show the types of clouds. where they are headed. and how fast they are moving. This radar image shows several tornado and thunderstorm warnings.
风暴追逐者还会扫描天气图、卫星图片和雷达图像,以寻找坏天气即将到来的线索。 天气地图风暴报告可以显示过去导致大风暴的云和风的模式。 如果同样的情况再次发生,暴风雨可能就要来了。 卫星图片地球上空的卫星拍摄云的照片。 风暴追逐者通过观察云层的形状和运动来预测极端天气。 从太空看飓风就像螺旋。 雷达图像雷达设备发出的信号被云层内的雨滴和水滴反射。 计算机将数据转换成彩色云图,显示云的类型。 他们要去哪里。以及它们移动的速度。 这张雷达图像显示了几次龙卷风和雷暴警报。
Inside the Storm The storm chasers have located a forming storm, and it looks like a big one! Radar maps guide the team to the storm's location. They drive in an armored truck filled with weather instruments. They place sensors called turtles on the ground in the path of the storm. The turtles will gather data from inside the storm. The truck is equipped with side armor that blocks the wind from getting under the truck and flipping it over. Strong spikes attach the truck to the ground. The storm chasers are inside the tornado, but the truck keeps them safe. The job is dangerous, but storm chasers love the thrill of being inside a storm.
风暴内部风暴追逐者已经定位了一个正在形成的风暴,它看起来像一个大风暴!雷达图指引摄制组到达风暴的位置。 他们开着一辆装满气象仪器的装甲卡车。 他们在风暴路径的地面上放置了一种叫做海龟的传感器。 海龟们将从风暴内部收集数据。 卡车配备了侧装甲,以防止风从卡车下面吹翻。 结实的钉子把卡车固定在地面上。 风暴追逐者在龙卷风内部,但卡车保证了他们的安全。 这项工作很危险,但风暴追逐者喜欢置身于风暴中的刺激感。
