Q: 风速单位是什么

Q: What is the wind velocity unit?

A: 单位是m/s

A: It is m/s.

 

Q:为什么用10个模型的果作天气的预测,而不是用真的天气史数据?

Q: Why you use 10 forecast models rather than in-situ measurement data?

A:气象局预测数据会从不同的角度去建模,预报气象数据。但是怎么把些模型的行模型融合,是一个挑

A: The Met Office uses different models to forecast the weather. The challenge is how to integrate the results of these models.

 

Q:英国气象局每天会运行 10 个不同的预测模型,得出稍有不同但基本准确的预测结果。然而,天气预测的准确率通常 90%-95%以上。

怎么理解预测的准确性?

Q: The weather forecast is usually 90-95% accurate.  The Met Office runs 10 different forecast models every day and these each results in slightly different forecasts each more or less correct.

How to understand the forecast accuracy?

A: The forecast accuracy = | forecast of wind velocity – in-situ measurement of wind velocity | / in-situ measurement of wind velocity

 

Q:每天3点钟10架推进式无人运输飞行器将从伦敦海德公园飞往英国其他10个目的地城市。“这句话的意思是不是说,路线的第一个地点是(142328),第一个时间是0300

Q: “At 3:00 every morning, 10 propelled cargo balloons set out from Hyde Park London to 10 destination cities in Britain.”

Does it mean that the first coordinate is (142, 328) and first time is 03:00?

A:是的。

A: Yes, exactly.

 

Q: 飞机可以选择绕行,来躲避风暴吗?

A: 可以。在限定的区域内绕行。

Q: Is the balloon allowed to detour to avoid the storm?

A: Yes, it is. But only to fly in limited area.

 

Q: 为什么要限定区域大小?

A: 是因为跨越区域后,可能飞到领国上空去了。还有一点气象局的数据只会预报本国的气象。

Q: Why there is a limitation of flight area?

A: In order to keep the balloon from flying to other counties, as the Met Office only predict the weather of the UK.

 

Q:请问提交的结果中是否需要包括3:00在起点的记录。

Q: Should the submission file contains the record of 3:00 at the starting point?

A: 包括300

A: Yes, 3:00 should be included.

 

Q:如果飞机起飞的时候,有风暴,到了4点才能飞,那么需要把3点到4点的停留信息,记录在结果中么?

Q: If there is a storm at 3:00 and the balloon has to take off until 4:00, should I record the stay information from 3:00 to 4:00 in the result?

A:每隔两分钟的记录都必须记录在文件里面

A: Yes. Records of every two minutes should be contained in the submission file.

 

Q:为了躲避风暴,在风暴来临之前中途停留或在起点等待,然后风暴袭击该点,等风暴平息之后再出发,飞机在风暴期间为停止状态,飞机可以不被摧毁吗?

Q: Can the balloons stay before the storm or wait at the starting point until the storm subsides to avoid crash?

A:可以停留在不受风暴影响的区域,但是每隔两分钟的记录还是必须记录在文件里面。

A: The balloons are allowed to stay in the area unaffected by storms, but records of every two minutes must be contained in the file.

 

Q:有一个规则我不清楚,如果起飞的时候有风暴,所以没有起飞,但是结果文件中也是有这段时间的记录的,评测程序中这段路线是不是会被误判错。

A:3:00就认为已经起飞了,在当前区域块上空了。

Q: I don’t quite understand this: if the balloon doesn’t take off at 3:00 because of a storm but the result file contains the record of this period of time, will the evaluation system misjudge this?

A: The balloons default to take off over the current block area at 3:00.

 

Q:请问要是飞行器在18小时内没有到达目的地的惩罚是什么呢,是20*60还是24*60呢。

Q: what’s the penalty if the balloon doesn’t reach the destination within 18 hours? 20*60 or 24*60?

A: 24*60,算坠毁。

A: 24*60, and it’s considered as a destroy.

 

Q:测试预测的天气数据我们是每天获得全部的数据吗?还是我们路线规划必须严格按照只有提前一个小时的天气预报进行规划呢。

A:测试数据每天可以获得全部预报数据

Q: In terms of the forecast data for testing, do we get the data of the whole day or hour-by-hour?

A: The forecast data for testing offers the data of the whole day.

 

Q:坠毁的航班需要提交吗?

A:坠毁的航班不用提交,评测自动检测缺失航班,并加上惩罚值

Q: Do I have to submit the destroyed flights?

A: No, you don’t need to submit the destroyed once. The evaluation system will automatically detect the missing flights and add on penalty value.

 

Q:最后的提交结果50个飞行器路径输出的先后顺序的有关系吗

A:没有关系

Q: Is there any difference in the sequence of the 50 submission results?

A: No difference in the sequence.
