Weather patterns in Atacama cause large changes in barometric pressure. Pressure drops when storms come from the Pacific Ocean. Pressure rises when dry air comes from the Andes Mountains.
Atacama's high elevation and desert landscape make the air pressure low. Mountains block moist air from the ocean. Valleys allow cold air to sink and settle.
In summer, pressure is higher due to dry air from the Andes. In winter, pressure is lower due to moist air from the ocean. This leads to more clouds and fog.
Atacama has a desert climate, which means little rain and big pressure changes. This makes the weather extreme, with sudden changes in temperature and humidity.
