What does "LTG ICCCCG" convey in terms of lightning activity?

• A. Only in-cloud lightning is present
• B. Lightning between three different types of clouds
• C. Lightning intra-cloud, cloud to cloud, and cloud to ground
• D. Only cloud-to-ground lightning

Answer: (C)

The indication "LTG ICCCCG" is a specific METAR code that details the types of lightning observed. The "LTG" prefix denotes lightning, and the subsequent letters provide information about the nature of that lightning. In this case, the code breaks down as follows: - "I" stands for intra-cloud lightning, which occurs within a single cloud. - "C" stands for cloud-to-cloud lightning, which occurs between different clouds. - The last "CG" denotes cloud-to-ground lightning, which is the type of lightning that strikes from the cloud down to the ground. Thus, the entire expression together — "ICC" and "CG" — tells us that all three types of lightning activity are present: intra-cloud, cloud-to-cloud, and cloud-to-ground. This comprehensive description is why the correct choice is C, as it encapsulates the full range of lightning activity indicated by the observed conditions. Understanding this terminology is critical for interpreting METAR reports effectively, especially in terms of weather hazards related to thunderstorms. Other interpretations would not accurately capture the range of lightning types described in the METAR code.
