Thunderstorms of the world
Lightning strikes Earth some 1.4 billion times per year. More than 2,000 thunderstorms are happening simultaneously over the Earth with some 100 flashes every second. Only some 20 – 30% of strikes go from cloud to ground.
Lightning is more frequent over the land because the land surface in the day gets more heated, causing more intense air convection, what in turn leads to lightning.
Areas far away from the equator only occasionally experience lightning flashes, while closer to the equator lightning is very common. Most frequent lightning flashes are in the following areas of the globe:
- Central Africa;
- Northern Colombia and Venezuela. See the description of the phenomenal Catatumbo Lightning;
- Southern Brazil and Paraguay;
- Southern slopes of northern Himalayas.
In each of these locations take place such intense thunderstorms which are unseen in Europe. But out of these locations, Central Africa has the highest intensity of lightning bolts.
Kifuka – world record holder of lightning intensity
Kifuka is located just 300 km south from the equator, in a zone of tropical wet climate. The summer lasts here for a whole year and thunderstorms are frequent throughout the whole year. Masses of humid air have traveled 1,700 km from the Atlantic ocean over the second-largest rainforest of the world and finally, they have reached the very first mountains: hills around Kifuka reach a height up to 1 kilometer above the sea level.
As a result, Kifuka experiences violent thunderstorms unprecedented anywhere else in the world: each square kilometer experiences approximately 158 lightning strikes per year – one lightning strike per 6,300 square meters. For comparison in Europe north from Alps density and frequency of lightning is 150 – 300 times lower.
World record of Kifuka was announced six-seven years ago and the research goes on since then. Wondermondo does not possess information whether Kifuka still holds the record.
How are the lightning flashes counted?
Researchers of lightning obtained powerful instrument with the launch of NASA’s Lightning Imaging Sensor (LIS) on Japanese satellite in November 1997.
LIS detects the distribution and variability of all kinds of lightning in the tropical regions of our planet. The instrument records the time when lightning occurs, measures the radiant, determines location. It manages to detect even most of the day lightning. This information is of high value to climate researchers because it helps to understand the mechanism of global storm convection and dynamics.
Data from LIS, including fairly recent data, is available here.
Kifuka is included in the following list:

There are not too many landmarks in this category – but several of them are highly unusual and unique.
This new book provides a focused set of topics suitable for advanced undergraduate or graduate courses on lightning. It presents the current state of the art in lightning science including areas such as lightning modeling, calculation of lightning electromagnetic fields, electromagnetic methods of lightning location, and lightning damaging effects and protective techniques.
Does lightning strike twice in the same place? How does a lightning rod work? What is ball lightning? How many thunderstorms are in progress in the world at any one time? Why does lightning zigzag? What is St. Elmo’s Fire?
