[Weather Useful Information] Can satellite images show the strength of cold air above? What is "offshore distance"? Supervised by Sysmet Co., Ltd. Weather Forecaster.
Thank you for always watching. The last weather-related information for 2024 will introduce a theme unique to winter. As December has arrived, the temperature has dropped significantly. During this time, the term "cold air aloft" is often heard in weather forecasts. The phenomena of cold air aloft and clouds observed by the Himawari weather satellite can be viewed as images on the Japan Meteorological Agency's website. In fact, those images contain indicators that suggest the strength of the cold air aloft, in addition to the movement and shape of the clouds. This is referred to as "offshore distance." This time, I would like to introduce this "offshore distance." It may sound like a difficult term that is not very familiar, but it can actually be easily checked. Table of Contents 1. What is offshore distance? 2. Offshore distance and the strength of cold air aloft 3. Conclusion *For more details, please visit our website or feel free to contact us.

"Point Weather Forecast" KIYOMASA PRO has obtained "VE Evaluation"!
The weather risk management mobile "KIYOMASA PRO" has received the highest rank VE evaluation (proven effective technology) in NETIS (New Technology Information System of the Ministry of Land, Infrastructure, Transport and Tourism). NETIS Number: KT-230016-VE Technology Name: Weather Risk Management Mobile "KIYOMASA PRO" ◆ Benefits of VE Evaluation 1. Additional points for technical proposals and creativity in construction performance evaluation It is expected that evaluation points will improve during technical proposal submissions for bidding and at the completion of construction (construction performance evaluation). This increases competitiveness compared to using other weather information services, and further recognition from clients and contractors is anticipated. 2. Simplification of procedures Typically, the creation and submission of the "Effectiveness Survey Form," which is required within 30 days after construction completion, will not be necessary, simplifying post-construction procedures. 3. Long-term availability The VE evaluation obtained this time is scheduled to be published for 10 years starting from the year following the initial registration (2024). It can be used over a long period, providing peace of mind. Above all, it is recognized as a superior technology compared to conventional methods, offering tremendous effectiveness as a weather risk management tool to protect sites and workers from localized heavy rain, lightning, and gusts.
