气温年较差

5个地理种群的SCP与当地气温年较差呈显著负相关，但与年均温无关。

℃, and the SCP was negatively related to the yearly margin of ambient temperature for the geographical populations , but not to the monthly or yearly temperatures they experienced .

近40年江苏省气温年较差异常的演变及其海气背景场特征

Variation of 1961 - 1998 Annual Temperature Anomaly in Jiangsu and Its Air-Sea Background Features

1976年起季节循环有明显变化，冬季变暖夏季变凉，月平均气温的年较差比前43年减小1.7℃。

Since 1976 strong changes in seasonal cycle have taken place , with winters becoming warmer and summers colder . The annual range of monthly mean temperature in the latest 21 years was 1.7 ℃ less than in the earlier 43 years .

但是，气候构型与现今截然不同，具有气温高、年较差小、降水波动大的特点。

However , the climate composite at that time was different from the present one , and was characterized by higher temperature , small annual range , and big fluctuation in precipitation .

显著表现为气温日较差、年较差大；夏季和白昼太阳辐射强烈，夜间天空长波辐射大；空气干燥，降水稀少；植被稀薄，风疾沙多。

The Significant performance is there is significant difference between diurnal temperature range and annual temperature range . The solar radiation is strong in summer and day-time and radiation of long wave is large in sky at night . The air is dry and the rainfall is rare .

若尔盖高原内部年平均气温0.6～3.3℃，气温年较差19.1～21.2℃，已不具备多年冻土形成和保存的气候条件。

Field investigation shows no permafrost in the interior of the Zoige Plateau . The mean annual air temperature is 0.6 ~ 3.3 ℃, and the annual range of air temperature is 19.1 ~ 21 2 ℃ .
