Precipitation Events

A região metropolitana de Recife-PE tem apresentado constantes casos de inundações decorrentes de eventos de precipitação extremos. Estas inundações afetam significativamente a dinâmica da população uma vez que os alagamentos dificultam a mobilidade urbana, inundam casas, desencadeiam deslizamentos de encostas, retardam as atividades de infraestrutura da cidade, etc. Tendo em vista os fatos apresentados, este trabalho busca apresentar a interrelação entre os eventos extremos de precipitação, suas causas (sistemas meteorológicos principais) e a dinâmica social da região baseado no conceito da geografia do clima. Para isso, utilizou-se da análise descritiva dos dados de precipitação diários de 2000 a 2010 de Recife-PE fornecidos pelo LAMEPE (Laboratório de Meteorologia de Pernambuco). Os principais resultados destacam que nestes últimos dez anos, o ano de 2000 (considerado ano de La Niña) e o de 2005 e 2010 (anos de El Niño) foram os de maiores ocorrências de eventos extremos. Palavras-chave: Sistemas atmosféricos, dinâmica da população, urbanização, região metropolitana.   An Climate Geography Approach on Extreme Precipitation Events in Recife–PE   ABSTRACT Recife-PE metropolitan area has shown constant cases of flooding caused by extreme precipitation events. These floods significantly affect population dynamics, since, flooding difficult urban mobility, flooding homes, triggering landslides, slowing the activities of the city's infrastructure, etc. Given the facts presented, this work objective to show the interrelationship between the extreme precipitation events, their causes (major weather systems) and social dynamics of the region based on the concept of geography climate. For this, used descriptive analysis of daily rainfall data from 2000 to 2010 in Recife-PE, provided by LAMEPE (Meteorological Laboratory of Pernambuco). The main results point out that over the past ten years, the year 2000 (La Niña years considered) and the 2005 and 2010 (El Niño years) were the highest occurrences of extreme events. Keywords: atmospheric systems, population dynamics, urbanization, metropolitan area.

Perekonomian Provinsi Nusa Tenggara Timur secara sektoral masih didominasi sektor pertanian.Tanaman jagung menjadi salah satu produksi tanaman pangan terbesar berdasarkan data dari Dinas Pertanian dan Perkebunan Provinsi Nusa Tenggara Timur tahun 2015. Peningkatan produksi pertanian dapat dilakukan melalui berbagai strategi adaptasi dan upaya penanganan bencana, salah satu upaya tersebut adalah dengan penyediaan informasi iklim terkait penentuan daerah-daerah rawan kekeringan. Tujuan dari penelitian ini adalah untuk mengetahui sebaran wilayah rawan kekeringan lahan jagung bulanan di Provinsi Nusa Tenggara Timur saat kondisi El Nino dan La Nina dengan periodeisasi bulanan januari hingga desember. Data yang digunakan dalam penelitian ini adalah data curah hujan rata rata bulanan di 19 pos hujan di Provinsi Nusa Tenggara Timur dan suhu udara rata-rata bulanan dihitung menggunakan pendekatan teori Brack dengan titik referensi Stasiun Klimatologi Lasiana Kupang. Periode dari masing-masing data yang digunakan adalah dari tahun 1991 dan 1997 digunakan sebagai tahun El Nino dan tahun 1999 dan 2010 digunakan sebagai tahun La Nina. Metode yang digunakan untuk menentukan tingkat rawan kekeringan dengan menggunakan pembobotan berdasarkan penjumlahan bobot tipe iklim Oldeman dan bobot ketersediaan air tanah. Hasil penelitian menunjukkan sebaran daerah kekeringan di Provinsi Nusa Tenggara Timurpada tahun el nino lebih luas dibandingkan tahun la nina.
