问题 综合

图20示意北半球某地区1月海平面等压线分布(单位:hpa),读图回答问题。(13分)

(1)用箭头   在图中C处画出此时的水平气压梯度力的方向。(1分)

(2)在图中用箭头     分别画出甲、乙两地的风向。(2分)

(3)与丙地相比,丁地风速较      (大、小),理由是                  。(3分)

(4)从阴晴角度考虑,A地天气         。仅考虑天气因素,A、B两地中昼夜温差小的是     ,原因是                                             (5分)

(5)该月份我国华北地区盛行   风;再过六个月,我国华北地区盛行  风。 (2分)

答案

(13分)

(1)由C点指向东南。(1分)

(2)甲地西北风   乙地偏南风(2分)  

(3)小(1分)  丁地等压线稀疏,水平气压梯度力小 (2分) 

(4)晴朗 (1分) B (1分)   B地(为低气压中心,)多阴雨天气,(1分)白天大气对太阳辐射削弱作用大,气温较低;(1分)晚上大气逆辐射较强(对地面的保温作用较明显),气温较高。(1分)

(5)西北风(偏北风)(1分) 东南风(偏南风)(1分)

题目分析:

(1)水平气压梯度力的方向为垂直于等压线,由高压指向低压。

(2)画风向的步骤①绘制水平气压梯度力,②结合地转偏向力绘制风向。

(3)丁地等压线稀疏,所以风力较小。

(4)A受高压系统控制,所以天气晴朗。B处受低压控制,阴雨天气为主。晴朗天气昼夜温差大,阴雨天气昼夜温差小,因为阴天白天气温比晴天白天气温低,晚上大气逆辐射强气温比晴天晚上气温高。

(5)冬季我国华北地区盛行西北风,过6个月华北进入夏季,夏季吹东南风。

For an owl (猫头鹰) with one-metre wingspan, the sky should be the limit. But Troy prefers his bird’s eye view to be no higher than 5 feet 10 inches. The one-year-old owl has an inconvenient symptom: he’s afraid of heights. After an unfortunate start in life when he fell from his nest by accident, Troy was raised by Gareth Tonen, a handler (饲养员), who just happens to be 5 feet 10 inches tall.

As a result, Troy has grown up without any great ambitions of his own. When it comes to trees, he can’t see what is about and would prefer to fly along at Mr. Tonen’s side. Only when the 25-year-old handler climbs up a tree can Troy be tempted to leave his comfort zone and join him.

Ashley Smith said, “ Troy’s fear of heights was a result of forgetting how to be a bird. He’s been in captivity (被圈养) for as long as he can remember and has never been higher than his handler can lift him. He sees himself as more of a human than an owl, and he doesn’t know how to sit in trees or hunt. Gareth has to almost act like an owl to get Troy to behave like one.”

As a result, a daily tree climb has become part of Troy’s – and Mr. Tonen’s – routine. Ladders have been fixed so Mr. Tonen can climb into the trees and call for Troy, who will fly up and join his handler but go no higher. Most of the time he flies down again, but occasionally Mr. Tonen has to carry him back to ground level. The afternoon ends with a meal of mouse, rabbit or his favorite, chicken.

Mr. Tonen said, “He now looks upon me as his mum or dad. He’s gaining more confidence and if I have to carry on climbing up trees with him then we’ll do what it takes for him to be a high flyer.
