The heavy snow cover was localized in Southern Sorachi Subprefecture. The maximum snow depth (208cm) and long-term snow cover (163days) in that winter set new records for data collected by the Japan Meteorological Agency in Iwamizawa. Results of regression analysis showed that the combination of a strong monsoon condition and low air temperature lead to the record-breaking maximum snow depth and long-term snow cover. The flames of plastic greenhouses were destroyed by the settlement force of snow cover that exceeded the height of the base of curved roof. The return period (the recurrence interval) of maximum snow depth (208cm) is 73 years, and the return period of maximum snow depth exceeding the base of the curved roof of a flame (145cm) is 4 years. The return period of long-term snow cover is 83 years. Hard snow mold diseases occurred because of long-term snow cover and heavy rain in September 2011. The last day of long-term snow cover (April 25) in 2012 is also a new record for data estimated by Iwamizawa JMA station snowdepth data. The return period of the day is 42 years. The delay of the agricultural calendar recovered in 2012., 2011年から2012年にかけて豪雪が発生し, 積雪調査の結果, 南空知地方に集中したことが明らかになった。岩見沢での最深積雪(208cm)や長期積雪期間(163日)は, 気象庁統計史上最大であった。重回帰分析の結果, 冬型と低温が要因として説明できた。農業雪害として, 積雪深がハウス骨組みの肩を超え, 沈降力により倒壊被害が多数生じた。今回の積雪深の再現期間は73年になり, 肩(145cm)を超える再現期間は4年であった。長期積雪期間の再現期間は83年になり, 9月多雨の影響もあり, 秋まき小麦の雪腐病被害が甚大となった。消雪日は4月25日と最も遅くなった(再現期間42年)が, 生育遅れはその後回復した。}, pages = {15--22}, title = {平成24年南空知豪雪による農業雪害とリスク評価}, volume = {203}, year = {2014}, yomi = {イノウエ, サトシ and ヒロタ, トモヨシ and ハマサキ, タカヒロ and ネモト, マナブ} }
