中文說明

新冰河期要發生了嗎?地球平均溫度越來越高,以離南極最近的國家—紐西蘭為例,勢必在未來一世紀中上升4度(周邊國家上升超過6度)。以科學觀點而言,在紐西蘭發生的這種氣溫變化現象,學者們稱之為 “SAM”(南極震盪),通常出現在信風帶所環繞的南極海域。然而近期研究也指出,位於紐西蘭境內的南極震盪變化會造成夏季期間水氣減少,降雨轉移至其他季節。有一個更大的問題是乾旱對莊稼種植所產生的影響,因為只要土壤中所含的水分越低,對該季收成的影響越大…

Global Warming in New Zealand

For many environmentalists, the world seems to be getting warmer. As the nearest country of South Polar Region, New Zealand has maintained an upward trend in its average temperature in the past few years. However, the temperature in New Zealand will go up 4 in the next century while the polar region will go up more than 6. The different pictures of temperature stem from its surrounding ocean which acts like the air conditioner. Thus New Zealand is comparatively fortunate.


Scientifically speaking, this temperature phenomenon in New Zealand originated from what researchers call “SAM” (Southern Annular Mode), which refers to the wind belt that circles the Southern Oceans including New Zealand and Antarctica. Yet recent work has revealed that changes in SAM in New Zealand have resulted in a weakening of moisture during the summer and more rainfall in other seasons. A bigger problem may turn out to be heavier droughts for agricultural activities because of more water loss from soil, resulting in poorer harvest before winter when the rainfalls arrive too late to rescue.


Among all the calamities posed by drought, moisture deficit ranks the first. Moisture deficit is the gap between the water plants need during the growing season and the water the earth can offer. Measures of moisture deficit were at their highest since the 1970s in New Zealand. Meanwhile, ecological analyses clearly show moisture deficit is imposed at different growth stage of crops. If moisture deficit occurs around a crucial growth stage, it will cause about 22% reduction in grain yield as opposed to moisture deficit at vegetative phase...
