Not entirely certain but, I would say from the definition of the word erratic, erratic rainfall refers to unpredictable rainfall. Non-uniform rainfall. Like when you know its rainy season but the weather forecast says there would be little or no rainfall. You leave the house and get dripping wet after 5 minutes of rain! Reminds me of the Nigerian meteorological services (Weather forecasting corporation)

rainfall
Deserts get little rainfall and some of them are quite hot - but not all. There are cold deserts also.
Arctic and Tundra biomes are both characterized by low temperatures and little rainfall. Alpine biomes also have low temperatures but have more rainfall.
There isn't much rainfall in the arctic, about 6 to 10 inches a year including melted snow. Some of the worlds greatest desert get more rainfall than that. Much of the arctic has rain and fog in the summer. Even though there is very low rainfall the arctic lands can be very wet underfoot because the moisture evaporates very slowly and the drainage conditions are poor. :D
