Poke Bowl is delicious!! It's only $5 and this volume! Much better than Big Mac combo. 最近のお気に入り”ポケボール” 日本語で”ポキ”かな!? これで5ドル。吉野家的な感覚かなｗI survived from tremendous amount of Dynamics homework and presentation last 2 weeks. For dynamics class, we have been learning "waves", including lamb wave, sound wave, Rossby wave, equatorial Kelvin wave, inertial and internal gravity waves....many waves!! The homework ask you to derive all those waves and plot the pattern. gosh, my final homework paper has 15 pages long, including computational plots! In climate variability class, I presented about the paper "Elimination of Greenland Ice Sheet in a high CO2 Climate" by J.K. Ridley et al.published in 2005. It was very interesting article. What in the article is basically to see what's going to happen on the Greenland Ice Sheet if you give a climate forcing by increasing atmospheric CO2 amount by 1160ppm, 4 times greater than the preindustrial. Also, this study is the first experiment to use "two-way coupling" which is the General Circulation Model(GCM) combined with the regional Greenland Ice Sheet Model(GISM), so to get climate feedback between GCM and GISM by calculating the surface water budget, rate of ablation and calving, orography change of the ice sheet and bedrock, surface runoff and retention, variations of albedo with detailed surface features such as types of soil and vegetation....etc Briefly summarizing the result,
1. If you let the model run with CO2 amount of 1160ppm, it takes 3000 years for the 93% of all ice sheet over Greenland to melt.
2. During this period, freshwater input to the Atlantic ocean would cause the weakening of thermohaline circulation, the southerly shift of westerly flow and polar front due to the orographic change.
3. IF all ice melt in Greenland, the global average sea level would rise 7 meter with a peak rate of 5mm/yr. This is very unrealistic in terms of the current climatological aspect.
4.Instead of CO2 forcing, if taking a temperature forcing by increasing 12℃ as a global mean temperature, it would only take 1000 years for all ice in Greenland to disappear.
5. The rate of melting would accelerate when the rate of ablation increases, generating more ice-free area where increased surface temperature and decreased surface pressure cause ascending motion, which causes descending motion over high elevated ice sheet and warming more and more.
well, if I explain all here by typing, it would take more time than my 40 min presentation, so I stop here.. But personally I'm interested in this kind of topic. i.e. "Climatologically, what is going to happen in the future?"
By the way, today is my payday,,lol so I bought an upper wet suit because it's so cold being in the water these days.... Even though I say it's cold, the high is still 80s and low 70s. But more cloudy, rainy, and windy days blocking the sunshine.
今日、（働いてもないのにｗ）給料日って事もあり、上半身のウェットスーツ購入!!ハワイも本格的な冬が近づいてきたｗ 最高気温は27度とかだけど、雨期で曇りの日が多くなって太陽が顔を出さないから、足が地についてる分には涼しくて気持ちいいんだけど、海に30分入るともう体がブルブルブルブル！これじゃサメの餌食になる。
やっと気候のクラスのプレゼンも終わって1週間ほど余裕が出来そう。っていっても、学期末までに宿題5つ、プレゼン1つ、ペーパー1つと、最後の最後まで休ませてくれないのが大学院生活・・・・・ けどそれが終われば寒くもなく,
雪も降らず、異様な冬休みの始まりｗ 何もプラン考えてないや。 誰か来ないかな～
