The habit of continuously collecting various weather information related to the site is the key to enhancing safety!

In recent years, there has been a notable increase in heavy rain disasters, with both the frequency and duration of heavy rainfall events, as well as the number of landslide incidents, showing an upward trend. To avoid damage from localized heavy rainfall, it is important not only to monitor warnings and advisories but also to early detect "signs of localized heavy rain" from information about rain and clouds, and to make "comprehensive judgments" in conjunction with established criteria. The related catalog introduces a recommended flow for making judgments using weather information. Please utilize it to enhance safety on-site and for decision-making in operations. 【5 Weather Information Checkpoints】 ■ Are there any days or time periods in the coming week when it will rain? ■ Are there any advisories or warnings regarding rain? ■ Are there any advisory notifications concerning linear precipitation bands? ■ What is the expected rainfall during the forecasted time periods, and how much rain is expected each hour? ■ Is there a risk of strong precipitation areas approaching the site that could bring more rain than the site standards? *For more details, please refer to the PDF document or feel free to contact us.

Not just linear precipitation zones? By understanding signs and trends, we can detect indications more quickly.

I will introduce the "Mechanism of Localized Heavy Rainfall." When a large amount of warm, moist air flows into the lower atmosphere and cold air flows in from above, the atmospheric conditions become very unstable, leading to the development of cumulonimbus clouds. As cumulonimbus clouds form successively in the same location and move eastward, they create a linear precipitation zone, causing heavy rain to persist in the same area. The related catalog provides a more detailed explanation of why localized heavy rainfall occurs, including examples from the heavy rain in northern Kyushu. Please take a look. [Development and Continuation of Cumulonimbus Clouds] - When a large amount of warm, moist air flows into the lower atmosphere and cold air flows in from above, the atmospheric conditions become very unstable, leading to the development of cumulonimbus clouds. - Cumulonimbus clouds form successively in the same location and move eastward, creating a linear precipitation zone that causes heavy rain to persist in the same area. *For more details, please refer to the PDF materials or feel free to contact us.

We conducted an RTK accuracy verification of the GNSS reference station (Hi-Target Vnet6plus receiver + choke ring antenna) installed at our company building. Generally, with a single-frequency GNSS, once the baseline length exceeds 10 km, it becomes impossible to consider the path through the ionosphere as the same, and the difference in ionospheric delay becomes a significant source of error. By using dual-frequency GNSS, it is possible to correct the delay based on the differences in delay caused by the frequency of the radio waves; however, it is still said to be effective only up to about 10 km. Why is that? We have published the verification results on our blog.
