Dr. San Srianthamrong, environmental scholar Disclosure of data from the past 5 years, Bangkok rainfall Reiterating that the worst day of this year may not come again, take heart, and probably the worst year is yet to come.
Today (12 September) Facebook “Sunt Srianthumrong” or Dr. San Srianthamrong, an environmental scholar posted a message about the case stating that “Bangkok floods: in conclusion, it is agreed that there is a lot of water, a lot of rain, or is it poor management? Let’s look at the numbers from the last 5 years. I can tell you that. The worst day of this year may not come yet, so let’s do it. The worst year is probably yet to come.
Let’s analyze the numbers from the last 5 years. The numbers which, in my opinion, are good indicators of flooding or not flooding when it rains are daily numbers. due to the rain-like floods Most of them are caused by short-term drainage. The monthly rainfall value is suitable for flood analysis. Bangkok from the North The problem we had last week was the problem of flooding from heavy rain in the area on a daily basis
Table 1: Rainfall measured at the highest measuring station in 24 hours Figures from 1 August-10 September Czech level 100 mm The year 2017 has exceeded 100 mm for 3 days. Year 2018 over 100 mm. 0 days. Year 2019: over 100 mm. 0 days. Year 2020: over 100 mm 1 day. 2021: over 100 mm. 4 days. 2022: over 100 mm. 8 days. The six year period exceeds 100 mm, a total of 16 days, with 8 days in 2022. Graph 1: Rainfall measured at the top station in 24 hours, figures between August 1 and July 10. Check level 120 mm.
Year 2017 over 120 mm 0 days 2018 over 120 mm 0 days 2019 over 120 mm 0 days 2020 over 120 mm 1 day 2021 over 120 mm 2 days Year 2022 over 120 mm 6 days 6 years span is a total of over 1 2 9 mm day is 6 days in 2022 and all 9 days are in the last 3 years.
Graph 2: Average 7-day rainfall measured at the top station in 24 hours, figures from 7 August to 10 September 2017, the highest 66.9 mm, 31 August 2018, up to 50.3 mm, 9 September 2019, up to 24.9 mm, August 26, 2020, up to 70.4 mm, September 3, 2021, up to 85.0 m M. On September 1, 2022, the highest 99.9 mm On September 10, this year, a value of 99.9 is the highest record of the 7-day Moving Average found in the Bangkok area in 6 years. If we Looking at the red line, you can see that the record dash is very worrying that it may not end here.
Graph 3: Rainfall measured at the highest measuring station in 24 hours, 3 month numbers from August 1 to October 31, the graph indicates the future. We can see that over the last 5 years, the gray bar chart has a high bar. During the second half of the rainy season, which is mid-September to the end of October, it is more intense than the beginning of the rainy season, so this is a concern. “The worst day of the year may not be here yet” at the bottom of Table 1, which is the average of the first 10 days of September:
Year 2017 Average 60.0 mm Year 2018 Average 43.9 mm Year 2019 Average 24.2 mm Year 2020 Average 52.8 mm Year 2021 Average 54.4 mm Year 2022 Average 81.4 mm Breaking the record in September 2022 Average 81.4 mm Breaking the record in September 2020 on average, which is the early rainfall Bangko, which is the early rainfall from 1 September. very high And occurs several days in a row 2. Average rainfall 7 days, breaking the record for the last 6 years from August-October 3. Average rainfall for the first 10 days of September. The record is also broken 4. The number of days with rain over 100 mm breaks the record 5. The number of days with rain over 120 mm breaks the record 6. The big problem is It may not monthly averages have increased at all, but extreme days have increased enormously. This is the character of the Climate Crisis problem. Unbeatable statistics.
1. The highest amount of rain in a day The original record holder was 223 mm on October 14, 2017. News pictures from The Standard that day have been continuously heavy from the night, just one day and it’ n completely confused. Much heavier than last week. Sometimes I think this is just the beginning. This is not just the beginning of this year. But it may be a warning sign of a disaster that will come in the coming years as well. The more intense the Global Warming, the more we will come across Extreme Weather Events like this. A real disaster is more serious than a warning sign. And if seas rise even further in 2050, what worries me most right now is whether or not Bangkok and many of the surrounding areas will still be livable. If people do not pay attention and neglect environmental problems like this Most of us people see each other, but who are they, politics, pocket money, GDP, and all kinds of neglect.
To tell the truth, next time I will bring the flood map in 2050 to analyze along with global warming. Then let’s see that How do normal human beings survive? Remember, This is Just the Beginning. PS From people who don’t invest in real estate in Bangkok at all.”
