hujan deras mendera Jakarta akhir minggu kemaren. Sabtu, keluyuran di wilayah kebayoran lama, dan hujannya dahsyat. Namun apa yang terjadi, tidak begitu di wilayah Jakarta Timur yang terang benderang!!!

dan di hari Minggu, dalam perjalanan pulang dari berjalan-jalan di daerah Jakarta Utara, awan tebal hitam menggantung di langit dengan petir menyambar-nyambar dan menggelegar (sebenernya g denger sih,karena di dalem mobil, cuma kata orang-orang sih menggelegar). Gwe agak aneh dengan formasi awan yang berbentuk lingkaran seperti awan badai. Sangat tumben sekali di wilayah Jakarta. Mungkinkah terjadi badai di atas sana. Gwe pikir ini adalah tipe awan Cumulonimbus.

Cumulonimbus (Cb) is a type of cloud that is tall, dense, and involved in thunderstorms and other intense weather. It is a result of atmospheric instability. These clouds can form alone, in clusters, or along a cold front in a squall line. They create lightning throught the heart of the cloud. Cumulonimbus clouds form from cumulus clouds (namely from cumulus congestus) and can further develop into a supercell, a severe thunderstorm with special features. (wikipedia)
Cumulos Clouds
The word cumulus comes from the Latin word for a heap or a pile. Cumulus clouds are puffy in appearance. They look like large cotton balls. Cumulus clouds usually form when warm, moist air is forced upward. As this air rises, it is cooled. If it is cooled below its dew - point temperature, condensation will occur. The size of a cumulus cloud depends on the force of the upward movement of air and the amount of moisture in the air. The largest cumulus clouds are caused by very strong upward movements of warm, moist air. The clouds that produce heavy thunderstorms in summer are a form of cumulus clouds called cumulonimbus. Cumulonimbus clouds may extend upward for hundreds of meters. (schoolscience)
