It's a Chinese weather app. It provides weather info for the Chinese version of H8 firmware.
It's in 1.0.7 firmware by mistake and will be removed in future firmware.
You can't unsinstall it, but you can disable it so it doesn't appear in my apps. Go Settings - More - Apps - All. It's listed at the bottom of apps list. Select it and choose 'Force stop' then 'disable'.
