Why does Vancouver receive more precipitation than kelowna?

Vancouver receives more precipitation than Kelowna primarily due to its coastal location and the influence of the Pacific Ocean. The mountains surrounding Vancouver create a rain shadow effect, where moist air from the ocean rises and cools, leading to increased rainfall. In contrast, Kelowna is located further inland and has a drier climate, resulting in less precipitation overall. Additionally, Vancouver's proximity to prevailing westerly winds contributes to its higher rainfall levels.
