If there is moist air, swift updraft, and an unstable atmosphere, a thunderstorm will develop.若存在潮湿空气、强烈上升气流以及不稳定的大气环境，雷暴便会发展形成 。

Thunderstorms always happen in summer. There are three stages of a thunderstorm: developing stage, mature stage, and dissipating stage. During the developing stage, it is full of updraft. During the mature stage, there is rainfall. During the dissipating stage, there are strong downdrafts.雷暴常发生在夏季。雷暴有三个发展阶段：发展阶段、成熟阶段和消散阶段。在发展阶段，上升气流旺盛；在成熟阶段，会出现降雨；在消散阶段，有强烈的下沉气流 。 Thunderstorms have three stages. The developing stage is full of updrafts, with moisture condensing into water droplets to form storm clouds. The mature stage has both updrafts and downdrafts, accompanied by heavy rain, lightning, and thunder. The dissipating stage features stronger downdrafts, with the storm dying out as warm moist air stops rising. 雷暴分为三个阶段。发展阶段：充满上升气流，水汽凝结成水滴，风暴云逐渐形成；成熟阶段：上升气流与下降气流并存，伴随大雨、雷电；消散阶段：下降气流占主导，暖湿空气停止上升，风暴逐渐减弱直至消失。

Thunderstorms are most likely to occur in summer.雷暴最有可能在夏季发生 。 Thunderstorms are most likely to occur in summer. Summer’s high temperature leads to strong convective currents in the air, which easily form cumulonimbus clouds (CBs) — the main source of thunderstorms. They can also occur in spring or autumn in some regions with unstable weather conditions. 雷暴最常见于夏季。夏季气温高，空气对流强烈，易形成积雨云（CB），而积雨云是雷暴的主要成因。在部分地区，春秋季天气不稳定时也可能出现雷暴。

For example, if I encounter a thunderstorm during flight, I will advise the controller of our situation and request an offset of 10 miles to the right or left of the track to avoid the thunderstorm.例如，若我在飞行中遭遇雷暴，会向管制员报告情况，并申请向航迹右侧或左侧偏移 10 海里以避让雷暴 。

Before flight, we can get weather information from the dispatching office, ATIS, or ATC. During the preflight briefing, we will discuss the weather information in the briefing room.飞行前，我们可从签派室、自动终端情报服务（ATIS）或空中交通管制（ATC）获取天气信息。在飞行前简报阶段，我们会在 briefing room（ briefing 一般指飞行前的任务、天气等简报会，可译为 “飞行准备室 / briefing 室” ，若需更明确，也可结合公司习惯，比如 “ briefing 室” 常用作 “飞行准备室” ）讨论天气信息 。

If there is an indication of a thunderstorm ahead of us, we will report the situation to ATC and request clearance to go round. Then we will change the course/route. When we are clear of the thunderstorm, we will rejoin the planned route.若前方有雷暴迹象，我们会向空中交通管制（ATC）报告情况，申请许可绕飞。随后我们会变更航线。当脱离雷暴影响后，我们会重新加入预定航线 。

If there is a thunderstorm at the airport and we are still on the ground, we will stop the aircraft and wait for the weather to improve. If we are flying in the air, we will hold to wait for the weather to improve or divert to the alternate airport.若机场有雷暴且我们仍在地面，会让飞机停场并等待天气好转。若在空中飞行，我们会盘旋等待天气好转，或改航至备降机场 。 If there is a thunderstorm at the airport, I will request to delay departure or change to another runway before flight. During flight, I will ask ATC for holding until the weather improves, or request diversion to an alternate airport. I will never attempt to take off or land in a thunderstorm to avoid hazards like lightning strikes. 若机场附近有雷暴，起飞前我会申请延误起飞或更换跑道；飞行中则向空管申请等待至天气好转，或请求改航至备降机场。绝不会在雷暴中尝试起降，以规避雷击等风险。
