いろいろな気候域と各種地表面における蒸発散量を比較するために, 新しく導入されたポテンシャル蒸発量(可能蒸発量)で蒸発散量と降水量を無次元化し, それらの気候学的な関係を求めた.裸地面においては, 降水量の少ない乾燥域では年蒸発量は土壌の種類によらず年降水量にほぼ等しいが, 降水量が増加すると年蒸発量は土壌の種類に依存するようになり, さらに降水量が増加すると無次元年蒸発量は土壌の種類によって決まる上限値をもち, 無次元年降水量(気候湿潤度)に依存しなくなる.上限値は保水性のよいローム質土壌で0.6〜0.9, 排水性のよい粗砂地で0.3程度である.森林では, 葉面積指数が大きく雨の日の濡れた樹体からの遮断蒸発量が多く, 蒸発散量は降水量または降水日数と共に増加する.しかし, この傾向は芝生地や牧草地では明瞭ではない.無次元蒸発散量は暖候期の水田や森林では0.7〜0.9, 浅い水面では0.7程度, 芝生など草地では0.5〜0.6, 夏のツンドラや乾燥域のオアシスでは0.5前後である.また, 乾期・雨期の明瞭な地域については, 精度の高い観測資料が少なく確定的ではないが, 無次元蒸発散量の年間値は年降水量の増加と共に大きくなり, その最大値は0.4程度(主として草地)〜0.8程度(主として森林)に収束するように思われる.この値からのばらつきは雨の集中性, つまり雨季・乾期の顕著さに依存すると考えられる.今後の研究では, 蒸発散量は相対誤差10%以内の精度で観測し, これらの数値を確定することが重要である.

A large number of forest fires were caused by unusual strong dry winds over northeastern Japan on 27 April 1983. The total area of devastated forest by these fires amounted to about 9, 000 hectare. The present paper explains this particular weather phenomenon and shows a method to predict the local wind speed under strong wind conditions.

In February 2005,Meijo and Nagoya Universities concluded an agreement with Nagoya University Hospital under which a resident faculty is stationed at the hospital.Nine graduate students are assigned to the resident faculty under whose guidance they engage in a variety of activities which include inpatient and outpatient pharmaceutical services under pharmacists and clinical research in collaboration with doctors at Nagoya University Hospital.In addition,our universities conduct practical training for fourth-year students for four-week periods each year from May to July.In 2007,a total of 41 students participated in the practical training at Nagoya University Hospital.Under the guidance of the resident faculty,graduate students instructed the students in activities conducted in hospital wards and the outpatient asthma clinic (we call this“age-mixing”).After the four-week training programs,a questionnaire survey was conducted to determine the participants’views concerning the training schedule,content of the training and the“Age-mixing Method”.The trainees had a favorable impression of the training with many selecting the responses“Our training went very well thanks to the support of the resident faculty”,“We learned a lot form graduate students”,“The Age-mixing Method is very useful for trainees”and“We realized that‘teaching is learning’”.The introduction of the Age-mixing Method not only allowed trainees to learn from graduate students,it also enabled graduate students to review and reinforce their knowledge and skills through teaching.We therefore believe that the Age-mixing Method is useful for both student trainees and graduate students.

The horizontal wind field of the typhoon, T9119,was analyzed using the surface wind data at the meteorological stations in Japan. In this analysis, observed wind speeds were corrected according to the surface roughness of each station. The 10-min mean maximum wind speed attained to 40-50ms^<-1> over flat surface in western Japan and the coastal area of Sea of Japan. The calculated wind field from the empirical formula compares favorably with the observation, and also suggests that wind speeds around Japan are enhanced by fast moving velocity of the typhoon nearly 100km h^<-1>. The wind storm of T9119 is as strong as those of the strongest typhoons which landed in Japan for recent 40 years. The gust factor in typhoon area slightly increases during recent 40 years, which result is mainly attributed to the increase of the surface roughness z_0 around each meteorological station.
