In chapter two, Master Subhuti warns Sun Wukong that he must protect himself from Three Calamities (sanzai lihai, 三災利害) sent by heaven to punish him for achieving immortality and defying his fate (fig. 1). These punishments come every half millenia in the form of destructive elements:
Though your appearance will be preserved and your age lengthened, after five hundred years Heaven will send down the calamity of thunder [lei zai, 雷災] to strike you. Hence you must be intelligent and wise enough to avoid it ahead of time. If you can escape it, your age will indeed equal that of Heaven; if not, your life will thus be finished. After another five hundred years Heaven will send down the calamity of fire [huo zai, 火災] to burn you. The fire is neither natural nor common fire; its name is the Fire of Yin [yin huo, 陰火], and it arises from within the soles of your feet to reach even the cavity of your heart, reducing your entrails to ashes and your limbs to utter ruin. The arduous labor of a millennium will then have been made completely superfluous. After another five hundred years the calamity of wind [feng zai, 風災] will be sent to blow at you. It is not the wind from the north, south, east, or west; nor is it one of the winds of four seasons; nor is it the wind of flowers, willows, pines, and bamboos. It is called the Mighty Wind [bi feng, 贔風], and it enters from the top of the skull into the body, passes through the midriff, and penetrates the nine apertures.  The bones and the flesh will be dissolved and the body itself will disintegrate. You must therefore avoid all three calamities (Wu & Yu, 2012, pp. 121-122).
These calamities are important because Monkey subsequently learns the 72 transformations in order to escape punishment by hiding under any one of a myriad number of disguises. Therefore, exploring the origins of the three calamities has merit.

The novel likely borrows from a Buddhist cosmological concept called the Three Calamities (sanzai, 三災). We first need some background before continuing. Buddhism recognizes a measurement of time called a Kalpa (jie, 劫), which can be many millions or even billions of years long depending on the tradition. Said traditions recognize between four and eighty kalpas (Robert & David, 2013, p. 409). The total of these respective ranges make up a Mahakalpa (dajie, 大劫), which is divided into four periods of nothingness, creation, subsistence, and finally destruction, each period being between one and twenty kalpas long (Robert & David, 2013, p. 496). The Three Calamities are responsible for the destruction of each Mahakalpa.
Kloetzli (1983) describes the cyclical destruction of each Mahakalpa by an element:
The destructions are of three kinds: those by fire, those by water and those by wind. […] The destructions succeed one another in the following sequence: seven by fire followed by a destruction by water. This cycle of eight destructions is repeated a total of seven times. This is then followed by seven more destructions by fire, followed by a final by wind. Thus there are 7 x 8 or 56 destructions by fire; 7 by water and a final 64th by wind [fig. 2] (p. 75).
Therefore, the Three Calamities from Journey to the West follow a similar cycle of destructive elements appearing at set time intervals: lightning, fire, and wind every 500 years in place of fire, water, and wind at the end of every Mahakalpa. And instead of destroying the universe, the elements are sent to kill those who have achieved immortality.

The earliest mention of Buddhism’s Three Calamities in Chinese writing that I know of appears in scroll one of the Pearl Forest of the Dharma Garden (Fayuan zhulin, 法苑珠林), a Chinese Buddhist encyclopedia published in 688. So there was plenty of time between this work and the publishing of Journey to the West in 1592.
Heavenly Tribulation (天劫 tiānjié) (重劫 zhòngjié) – in some novels, a trial encountered by cultivators at key points in their cultivation, which they must resist and ultimately transcend. Because immortal cultivation (generally) goes against the Will of Heaven, the Heavens will send down tribulations to oppress high-level cultivators who make progress towards Immortality, often right when they enter a new cultivation stage. This typically takes the form of a lightning storm, with extraordinarily powerful bolts of lightning raining down from the Heavens to strike at the cultivator (source).
The trial by lightning is exactly like the calamity of thunder mentioned by Master Subhuti.
The Wuxia/Xianxia (仙侠, “Immortal hero”) literature translator Deathblade (twitter) was kind enough to direct me to an example of a tribulation from a popular Chinese television show . The scene (video 1) involves a 20,000-year-old child immortal experiencing a trial by lightning. The heavenly bolts tear at his clothing and draw blood, but he survives the ordeal.
Video 1 – Start watching from minute 13:08.
Deathblade also directed me to an example from an online Xianxia novel called I shall Seal the Heavens (Wo yu feng tian, 我欲封天). Chapter 385(!) describes how the anti-hero Meng Hao (孟浩) uses a sentient heavenly treasure to protect himself from powerful bolts of lightning, which instead seek out and kill nearby spiritual cultivators on the cusp of immortality:
The Heavenly Tribulation boomed as one lightning bolt after another shot down onto Meng Hao, who held the meat jelly upraised in his hand to defend himself. The lightning would subsequently disperse into the area around him. Any nearby Cultivators would let out bloodcurdling screams. Soon, the air filled with the sounds of cursing and reviling.
Meng Hao didn’t care. This was something he had learned from Patriarch Reliance. When you con someone and then end up getting cursed by them, you must maintain your cool. It was really a realm unto itself.
Throughout the years, Meng Hao had conned many people, and had refined that skill to the very pinnacle. Therefore, he continued to redirect the descending lightning to the various Cultivators in the three thousand kilometer region.
Wherever he went, he was surrounded by a lake of lightning, along with plaintive cursing. What he left behind was scorched corpses.
To the Cultivators here, it was nothing but a massacre, a slaughter in which no one could do anything to fight back. They couldn’t attack him, nor could they flee as… they were horrified to discover that Meng Hao’ speed was incredible, even if he was being struck by lightning!
The character uses trickery to protect himself from the bolts just like Monkey intended to do with his transformations.
As I explained above, Wukong learns the 72 transformations in order to escape the heaven-sent punishments of thunder, fire, and wind. Monkey attains eternal life around his 342nd year when his soul is taken to Hell. He is immortal for over 160 years  at the time he’s imprisoned under Five Elements Mountain. This means his 500th year of immortality, the year that the calamity of thunder would be scheduled to strike him, takes place during his imprisonment under the celestial mountain. But this is never described in the story. I assume this is just one of many inconsistencies born from oral storytelling. Although, one could argue that, within the fictional universe, the thunder calamity was voided since Wukong was undergoing punishment at the behest of the Buddha.
1) The eyes, ears, nose, mouth, genitals, and anus.
2) Wukong serves in heaven twice: first “for more than ten years” and second “for over a century” (Wu & Yu, 2012, vol. 1, pp. 150 and 166). Then he is punished to 49 days in Laozi’s furnace (Wu & Yu, 2012, vol. 1, p. 189). But the narrative revels “one day in heaven is equal to one year on Earth” (Wu & Yu, 2012, vol. 1, pp. 150 and 167). So this means his turn in the furnace lasts close to fifty years.
