Penyemaian awan adalah suatu bentuk modifikasi cuaca dengan cara mengubah jumlah atau jenis presipitasi yang turun dari awan, melalui penyebaran zat-zat ke udara yang berfungsi sebagai kondensasi awan atau inti es, yang mengubah proses mikrofisika dalam awan. Tujuan yang lzaim adalah untuk meningkatkan presipitasi (hujan atau salju), namun supresi hujan es dan kabut juga secara luas dipraktikkan di bandar udara, di mana kondisi cuaca yang buruk terjadi.
Penyemaian awan juga terjadi disebabkan oleh nukleator es di alam, yang sebagian besar berasal dari bakteri.[2]
