This could mean oceans will rise even faster than forecast , and rising surface air temperatures appear to be to blame , the researchers report in friday ' s issue of the journal science 據(jù)路透社2月16日?qǐng)?bào)道,這種現(xiàn)象意味著,海平面上升的速度比人們預(yù)想的要快。
At the same time , during the course of 1km - resolutioned spatial interpolation for the daily surface air temperature in the reaches of yangtze rive , the altitudinal effect ca n ' t negligible 同時(shí)在長江流域內(nèi)地面日氣溫的1km分辨率的空間插值過程中,海拔高度對(duì)氣溫的空間分布的影響是不可忽視的。
Based on the monthly mean surface air temperature ( sat ) and monthly precipitation of 160 meteorological stations over china from 1951 to 2006 , the relationship between climate change and drying trend was analyzed in the last 56 years 摘要利用1951 - 2006年中國區(qū)域160個(gè)站的月降水及月平均氣溫資料,對(duì)中國區(qū)域近56a氣候要素的變化及其與干旱化聯(lián)系的事實(shí)進(jìn)行了分析。
Based on the daily surface air temperature data from 200 stations and daily precipitation data th from 739 stations during the second half of the 20 century , schemes for analyzing climate extremes were designed mainly according to percentiles of a non - parametric distribution and the gross errors in the daily data were removed based on a newly designed quality control procedure . the spatial and temporal characteristics of change of climate extremes over china were studied , the major conclusions are summarized as : th 1 . slight decrease trends were found for the 95 percentiles of daily maximum temperatures during summer , but larger increase trends were revealed for the 5th percentiles of daily minimum temperatures during winter , especially in northern china 本文利用中國20世紀(jì)后半葉較為完整的逐日溫度和降水觀測(cè)資料,設(shè)計(jì)了嚴(yán)格的資料質(zhì)量控制方法,以統(tǒng)計(jì)上的邊緣分布的客觀定義為主要依據(jù),確定了極端溫度和降水事件,研究揭示了近50年中國極端氣候事件變化的規(guī)律,得到以下主要結(jié)果: 1 .全國最高溫度的極端高值略趨下降;最低溫度的極端低值升溫趨勢(shì)顯著,這種增溫在冬季、在北方最顯著。
The variations of sea ice in the arctic ocean are simulated by using a improved high resolution hibler dynamic - thermodynamic sea ice model during 1979 - 1998 . the model is driven by surface atmospheric and oceanic forcing consists of geostrophic winds , surface air temperature , specific humidity , and longwave and shortwave radiative fluxes provided by international arctic buoy program ( iabp ) . the simulated results show that arctic sea ice have noticeable seasonal and annual variability 利用一個(gè)hibler海冰熱動(dòng)力模式,在改進(jìn)了其熱力部分和改變模擬范圍以及提高分辨率的基礎(chǔ)上,以北極國際浮標(biāo)計(jì)劃( iabp )提供的1979 - 1998年間逐日變化的日平均海平面氣溫場(chǎng),濕度場(chǎng),長短波輻射場(chǎng),風(fēng)場(chǎng),洋流場(chǎng),海洋熱流量場(chǎng)為強(qiáng)迫場(chǎng),模擬了上述20年間北極海冰的時(shí)空演變。
