Weather

Weather is the state of the atmosphere, to the degree that it is hot or cold, wet or dry, calm or stormy, clear or cloudy. Most weather phenomena occur in the lowest level of the atmosphere. Weather refers to day-to-day temperature and precipitation activity, whereas climate is the term for the averaging of atmospheric conditions over longer periods of time. When used without qualification, "weather" is generally understood to mean the weather of Earth.

In the Mega Man franchise, due to advanced technology, weather can change on both natural and unnatural ways. Depending on the weather, the terrain can be affected in a number of ways such as removing, obscuring, or adding obstacles.

Changes

 * In Mega Man 7, hitting a Tel Tel will change the weather in Cloud Man's stage.


 * In Mega Man X2 and Mega Man Xtreme 2, the Weather Crystal can change the weather in the Weather Control Center, Wire Sponge's stage.


 * In Mega Man X6, the Weather Analyze causes acid rain in Rainy Turtloid's stage. Acid rain can also appear in other stages due to the Nightmare Phenomenon.


 * In the first Mega Man Zero game, Contrainer can create strong winds, the rain in the area showing the wind's direction. TechTwister can generate a twister around itself.


 * In Mega Man Zero 4, the Weather Changing System (ウェザー・チェンジング・システム) allows players to decide the weather from the stages of the Einherjar Eight Warriors, which affects the terrain that Zero travels through. Stages which have a flashing border indicate a harder weather setting, whilst non-flashing ones will be easier. This can be changed right before the mission briefing. Playing on a harder stage may amplify the boss's strength as well as grant them the use of their EX Skill. Instead of finishing at S or A rank like previous games, completion of a stage in its harder form will grant Zero an EX Skill, while easier ones will not, and also result in a penalty at the Result screen.


 * In Mega Man Battle Network 6, Sky Town contains a weather control computer called Mr. Weather.
