Character Breakdown

Understanding 海抜 (かいばつ)

"海抜" means the height or altitude above sea level. It is commonly used in geography, weather reports, and travel contexts to describe how high a location is relative to the ocean's surface.

Usage and Context

This term is often used when discussing mountains, cities, or any place where elevation matters. For example, weather conditions can change significantly with 海抜, affecting temperature and air pressure.

Common Collocations

  • 海抜〇〇メートル: specifying the exact altitude (e.g., 海抜1000メートル)
  • 海抜が高い: indicating a high altitude
  • 海抜0メートル: sea level

Register and Nuance

"海抜" is a formal, technical term used in scientific, educational, and official contexts. It is not typically used in casual conversation unless discussing geography or travel.

Learner Tips

A common confusion is mixing 海抜 with "標高" (ひょうこう), which also means elevation but is often used specifically for mountains or landforms. 海抜 is a broader term referring to height above sea level regardless of the object.

Remember to use 海抜 when you want to emphasize the height relative to sea level in a precise or technical context.
