dry season A period each year durin

dry season A period each year during which there is little precipitation. In tropical climates (e.g. over much of India) the dry period is often in the winter season. In places in very low latitudes, two dry seasons may occur each year, between the northward and southward passage of the equatorial rains. In subtropical, Mediterranean, and in the climates found on the west coasts of continents, the dry season is in the summer.
The dry season is a yearly period of low rainfall, especially in the tropics. The weather in the tropics is dominated by the tropical rain belt, which moves from the northern to the southern tropics and back over the course of the year. The tropical rain belt lies in the southern hemisphere roughly from October to March; during that time the northern tropics have a dry season with sparserprecipitation, and days are typically sunny throughout. From April to September, the rain belt lies in the northern hemisphere, and the southern tropics have their dry season. Under the Köppen climate classification, fortropical climates, a dry season month is defined as a month when average precipitation is below 60 millimetres (2.4 in).[1]
The dry season has low humidity, and some watering holes and rivers dry up. This lack of water (and hence of food) may force many grazing animals to migrate to more fertile spots. Examples of such animals are zebras,elephants,[2] and wildebeest. Because of the lack of water in the plants, bushfires are common.[3]
Data shows that in Africa the start of the dry season coincides with a rise in the cases of measles—which researchers believe might be attributed to the higher concentration of people in the dry season, as agricultural operations are all but impossible without irrigation. During this time, some farmers move into cities, creating hubs of higher population density, and allowing disease to spread more easily.[4]
The rain belt reaches roughly as far north as the Tropic of Cancer and as far south as the Tropic of Capricorn. Near these latitudes, there is one wet season and one dry season annually. At the equator there are two wet and two dry seasons, as the rain belt passes over twice a year, once moving north and once moving south. Between the tropics and the equator, locations may experience a short wet and a long wet season. Local geography may substantially modify these climate patterns, however.
New data shows that in the South American Amazon rainforest, foliage growth and coverage varies between the dry and wet seasons—with about 25% more leaves and faster growth in the dry season. Researchers believe that the Amazon itself has an effect in bringing[clarification needed] the onset of the wet season: by growing more foliage, it evaporates more water.[5]However, this growth appears only in the undisturbed parts of the Amazon basin, where researchers believe roots can reach deeper and gather more rain water.[6] It has also been shown that ozone levels are much higher in the dry than in the wet season in the Amazon basin.[7]

musim kemarau Sebuah periode setiap tahun selama ada sedikit curah hujan. Di iklim tropis (misalnya lebih banyak dari India) periode kering sering di musim dingin. Di tempat-tempat di lintang sangat rendah, dua musim kering dapat terjadi setiap tahun, antara bagian utara dan selatan dari hujan khatulistiwa. Di subtropis, Mediterania, dan di iklim yang ditemukan di pantai barat dari benua, musim kemarau adalah di musim panas.
Musim kemarau adalah periode tahunan curah hujan yang rendah, terutama di daerah tropis. Cuaca di daerah tropis didominasi oleh sabuk hujan tropis, yang bergerak dari utara ke selatan dan kembali tropis selama tahun. Sabuk hujan tropis terletak di belahan bumi selatan kira-kira dari Oktober sampai Maret; selama waktu itu daerah tropis utara memiliki musim kemarau dengan sparserprecipitation, dan hari-hari biasanya cerah sepanjang. Dari April sampai September, sabuk hujan terletak di belahan bumi utara, dan daerah tropis selatan memiliki musim kemarau mereka. Di bawah Klasifikasi iklim Köppen, iklim fortropical, bulan musim kemarau didefinisikan sebagai bulan ketika rata-rata curah hujan di bawah 60 milimeter (2,4 in). [1]
Musim kemarau memiliki kelembaban rendah, dan beberapa lubang berair dan sungai mengering. Kurangnya air (dan karenanya makanan) dapat memaksa banyak hewan merumput untuk bermigrasi ke tempat yang lebih subur. Contoh hewan seperti zebra, gajah, [2] dan rusa kutub. Karena kurangnya air dalam tanaman, kebakaran semak yang umum [3].
Data menunjukkan bahwa di Afrika awal musim kemarau bertepatan dengan kenaikan dalam kasus campak-yang peneliti percaya mungkin dikaitkan dengan konsentrasi yang lebih tinggi dari orang di musim kemarau, karena operasi pertanian semua tapi mungkin tanpa irigasi. Selama ini, beberapa petani pindah ke kota, menciptakan hub kepadatan penduduk yang lebih tinggi, dan memungkinkan penyakit menyebar lebih mudah. ​​[4]
The sabuk hujan mencapai sekitar sejauh utara Tropic of Cancer dan sejauh selatan sebagai Tropic of Capricorn . Dekat garis lintang ini, ada satu musim hujan dan satu musim kemarau setiap tahunnya. Pada khatulistiwa ada dua basah dan dua musim kering, sabuk hujan melewati dua kali setahun, sekali bergerak ke utara dan sekali bergerak ke selatan. Antara daerah tropis dan khatulistiwa, lokasi mungkin mengalami basah pendek dan musim yang panjang basah. Geografi lokal dapat secara substansial memodifikasi pola iklim ini, namun.
Data baru menunjukkan bahwa di Amerika Selatan hutan hujan Amazon, pertumbuhan daun dan cakupan bervariasi antara kering dan basah musim-dengan sekitar 25% lebih daun dan pertumbuhan yang lebih cepat di musim kemarau. Para peneliti percaya bahwa Amazon sendiri memiliki efek dalam membawa [klarifikasi diperlukan] mulainya musim hujan: oleh tumbuh lebih dedaunan, itu menguap lebih banyak air [5] Namun, pertumbuhan ini hanya muncul di bagian terganggu dari lembah Amazon,. di mana peneliti percaya akar dapat mencapai lebih dalam dan mengumpulkan air hujan lebih. [6] Hal ini juga telah menunjukkan bahwa tingkat ozon jauh lebih tinggi di kering daripada di musim hujan di cekungan Amazon. [7]
