Do rainforests have droughts?

In what years did the Amazon rainforest experience drought?
During two events termed “droughts of a century” in 2005 and 2010, the Amazon rainforest changed temporarily from being a carbon sink to becoming a carbon source, thus contributing to the rising levels of CO2 in the atmosphere. In 2015/16 there was yet another severe drought in the region.
How does drought affect rainforests?
Under a changing climate, droughts that cause tree mortality may affect forest succession, with drier adapted species replacing wetter adapted species. Drought and wildfire can lead to loss of forests and invasion of fire-adapted nonnative shrubs and grasses.
Do tropical rainforests have a dry season?
There are no distinct wet or dry seasons as rainfall is high throughout the months. One day in a tropical rainforest climate can be very similar to the next, while the change in temperature between day and night may be larger than the average change in temperature during the year.
