The Kingdom of Saudi Arabia is currently experiencing weather conditions known as 'Al-Marawih', where thunderstorm clouds may develop into massive cumulonimbus clouds. This weather phenomenon is characterized by strong features, including heavy rainfall, hail, and accompanying strong winds, which can lead to flowing floods that may cover long distances.
Weather and climate expert Abdulaziz Al-Hussaini explained that this weather condition can transform into what is known as 'Sahab Al-Sarayat', which is notable for its ability to persist and travel hundreds of kilometers. On Saturday evening, the Al-Tuqai area north of Riyadh witnessed a powerful cloud that significantly affected the atmosphere.
Details of the Event
In discussing rainfall, former climate professor at Qassim University Dr. Abdullah Al-Masnad pointed out the fundamental differences between heavy rain and intense rain. Heavy rain is characterized by large amounts of water falling over a relatively long period, reaching up to 6 hours or more, which makes it regular and continuous.
This type of rain often results from extensive stratiform clouds accompanying dynamic weather systems. The danger of heavy rain lies in the accumulation that can lead to flooding in large valleys or complete saturation of the soil, causing significant infrastructure problems.
Background & Context
On the other hand, intense rain involves massive amounts of water falling in a short time, ranging from minutes to an hour. It is characterized by the large size of raindrops and the speed of precipitation, often resulting from giant cumulonimbus clouds. This type of rain is directly responsible for flash floods that can strike locations without sufficient warning.
Intense rain puts tremendous pressure on drainage systems, as the volume of falling water exceeds their capacity, leading to sudden flooding of streets and tunnels. Conversely, the danger of heavy rain is often gradual, allowing drainage networks a better chance to cope.
Impact & Consequences
The degree of danger varies between the two types, with intense rain considered more hazardous to cities and infrastructure. It surprises systems in a short time, potentially causing severe damage. While heavy rain, despite its dangers, allows for better management opportunities.
These weather conditions require preparedness and awareness from citizens, as necessary precautions must be taken to avoid potential risks. Relevant authorities also need to enhance drainage systems and update infrastructure to be capable of facing these challenges.
Regional Significance
These weather phenomena are part of the climate changes affecting the Arab region in general. The frequency of these phenomena is increasing, necessitating effective responses from governments and communities to mitigate potential damages. There should be cooperation among Arab countries to confront these climatic challenges.
In conclusion, it is clear that a good understanding of the differences between heavy and intense rain can contribute to improving emergency responses and reducing risks to communities.
