Distribusi spasial dan temporal petir di Sumatera Barat telah diteliti dengan menggunakan data satelit Tropical Rainfall Measuring Mission-Lightning Imaging Sensor (TRMM-LIS) selama 16 tahun pengamatan (1998-2013). Hubungan antara petir dan curah hujan diteliti dengan memanfaatkan data TRMM 3B43. Hasil penelitian menunjukkan bahwa petir di Sumatera Barat banyak terjadi di darat dengan densitas tertinggi terjadi pada bulan Desember, Januari dan Februari (DJF). Petir di darat banyak terjadi pada sore hari mulai jam 17.00 LST hingga tengah malam dan kabupaten Dharmasraya merupakan daerah yang memiliki densitas kilatan petir tertinggi terutama selama periode DJF. Siklus diurnal petir konsisten dengan siklus migrasi awan dari laut ke daratan Sumatera yang ditemukan oleh peneliti sebelumnya. Hubungan curah hujan dan petir di Sumatera Barat bervariasi antara satu kabupaten dengan kabupaten lainnya. Berdasarkan nilai regresi linier antara petir dan curah hujan terlihat bahwa daerah yang memiliki korelasi yang cukup kuat antara densitas petir dan curah hujannya adalah Kabupaten Solok,  Solok Selatan, Padang Pariaman, dan 50 Kota sedangkan daerah yang memiliki korelasi yang rendah adalah Kepulauan Mentawai, Pesisir Selatan, dan Agam. Dengan demikian, di beberapa kabupaten petir dapat menjadi indikator untuk penentu curah hujan tetapi tidak untuk beberapa kabupaten yang lain.Kata kunci: distribusi petir, Sumatera Barat, TRMM

Using the Time Of Group Arrival (TOGA) of sferics two year (Jan2003-Dec2004) annual average of about 3,200 and 1,200 cloud-to-ground (CG) flashes were recorded in the two larger islands, Viti Levu and Vanua Levu, Fiji. A two year average CG flash density showed maxima of 0.80 and 0.35 flashes/km2 per year in two islands. The diurnal variation showed peak activity between 14:00 hrs- 16:00 hrs LT and the seasonal variation showed enhanced lightning incidences during November-April. Data from Lightning Imaging Sensor (LIS) aboard the NASA Tropical Rainfall Measuring Mission (TRMM) satellite are also presented for the same period at the two locations. Lightning in a 10 km �10 km area was compared with total rain accumulation at a site midway in the area which shows good correlation.

The variation of the lightning activities over Sri Lanka and surrounded costal belt (5.750N-10.000N and 79.50E-89.000E) is studied using lightning flash data of Lightning Imaging Sensor (LIS) which was launched in November 1997 for NASA’s Tropical Rainfall Measuring Mission (TRMM). The LIS data for the period of 1998 to 2014 are considered for this study. The spatial and temporal variation of lightning activities is investigated and respective results are presented. The diurnal variation over the studied area presents that maximum and minimum flash count recorded at 1530-1630 Local Time (10-11UTC) and 0530-0630LT (00-01UTC) respectively. Maximum lightning activities over the observed area have occurred after the 1330LT (08UTC) in every year during the considered time period. The seasonal variation of the lightning activities shows that the maximum lightning activities happened in First inter monsoon season (March to April) with 30.90% total lightning flashes and minimum lightning activities recorded in Northeast monsoon season (December to February) with 8.51% of total lightning flashes. Maximum flash density of 14.37fl km-2year-1 was observed at 6.980N/80.160E in First inter monsoon season. These seasonal lighting activities are agree with seasonal convective activities and temperature variation base on propagation of Intra-Tropical Convection Zone over the studied particular area. Mean monthly flash count presents a maximum in the month of April with 29.12% of lightning flashes. Variation pattern of number of lightning activities in month of April shows a tiny increment during the time period of 1998 to 2014. Maximum annual flash density of 28.09fl km-2yr-1 was observed at 6.980N/80.170E. The latitudinal variation of the lightning flash density is depicted that extreme lightning activities have happened at the southern part of the county and results show that there is a noticeable lack of lightning activities over the surrounded costal belt relatively landmass.
