5. 98年洪水和08年南方大雪和厄尔尼诺现象有关吗？

厄尔尼诺是98年洪水的重要原因之一，但于08年大雪无关。厄尔尼诺对我国的影响表现为首先是台风减少，其次是我国北方夏季易发生高温、干旱，第三是我国南方易发生低温、洪涝，最后，在厄尔尼诺现象发生后的冬季，我国北方地区容易出现暖冬。
  08年大雪可能与拉尼娜现象有关，拉尼娜现象和厄尔尼诺现象相比，对气候的影响大致相反，常常出现在厄尔尼诺现象之后，与厄尔尼诺现象也称反厄尔尼诺现象。

6. 为什么2008年1月得大雪使南方很多城市得手机信号中断

因为大雪会阻碍或干扰电磁波的传播，手机信号靠的是电磁波。

7. 英文:2004年印度洋海啸及2008年南方大雪

On the morning of Sunday, 26 December 2004, there was a severe earthquake in the Indian Ocean off the coast of northern Sumatra, Indonesia. The earthquake measured 9.0 on the Richter scale and was followed by aftershocks ranging from 6.3 to 7.0 in severity in a zone 1,000 kilometres north to the Andaman Islands. The underwater earthquake also resulted in a powerful tsunami ('soo-na-mi', from the Japanese words meaning 'harbour wave'). The wave travelled quickly under the ocean, building to a wall of water up to 10 metres high when it reached the shallow coastal waters and causing massive destruction when it hit land. Without an effective warning system and disaster plan, many people did not know to move quickly to higher ground to escape the wave and its load of debris. In some places the sea receded for hundreds of metres before the wave rushed in. Curious people looking at this strange occurrence from the beaches did not recognise this as a sign of danger, and as a result were killed by the tsunami.

===================================

China's transport and energy systems have been caught in a perfect winter storm, with hundreds of thousands of people stranded during the peak travel season after train delays caused by heavy snow and power failures.

The power crisis, the worst in China for many years, has been caused by an acute shortage of the supply of coal, the country's staple fuel. Brownouts have affected about half of China's 31 provinces and regions

The problem has been amplified by unseasonally large snowfalls in northern and central China, but the root cause is Beijing's attempt to reimpose and tighten price controls on numerous commodities, such as coal and oil.

8. 为什么北方年年冬天都下大雪电力系统都正常,而南方下了一次大雪就大面积断电

温室效应导致气温上升，空气中含水量增大，南方的暖湿气流富含水气，遇到北方的冷空气形成剧烈摩擦导致南方大量降水。 

如果单纯降雪也好点，关键还降雨，还低温，所以电线上都是冰，随着降水增加，冰越来越多，把电线和线杆压塌了。 另外由于道路结冰，煤炭运不进来，造成电厂没有煤发电。

北方天气干燥，下雪的时候是单纯下雪，很少冬天下雨，所以电线上很少结冰，下完雪雪化了就没事了，而且北方产煤，电厂储存的煤炭比较多，不会缺煤。
