Welcome!

Hello, XavierLi, and welcome to Wikipedia! My name is Shalor and I work with the Wiki Education Foundation; I help support students who are editing as part of a class assignment.

I hope you enjoy editing here. If you haven't already done so, please check out the student training library, which introduces you to editing and Wikipedia's core principles. You may also want to check out the Teahouse, a community of Wikipedia editors dedicated to helping new users. Below are some resources to help you get started editing.

Critique Existing Article

2015_Pakistan_heat_wave Two things that I would like to change:

(1) A marginalized country as Pakistan is, the article does not have a comprehensive process description of the disaster. For example, there is missing information such as how did the heat wave took over the entire country, which region was affected most severely, what factor caused such a large number of deaths (obviously not the heat wave itself if everyone was properly hydrated). Also, there should be a detailed description of the aftermath of the incident, including the measures government would take to reduce causalities in the future.

(2) In the Contributory factors section, there are only descriptions of ideas or measures from government officials, which may be biased. Especially when the article mentions the official, Asif Shuja, said that the cause of this event is because of global warming, Intergovernmental Panel on Climate Change (IPCC) actually reported the same causality, which is far more convincing.

Proposed Project 1: Precipitation extreme and climate change (3rd choice)

There are several articles or paragraphs in articles that are talking about the relationship between extreme weather and climate change (see Extreme_weather and "extreme weather" section in Global_warming and Physical_impacts_of_climate_change). However, these articles mainly focus on hurricanes as a proxy of "extreme weather", and overlooks the general extreme precipitation events such as mid-latitude cyclones and fronts, that are also associated with climate change. The Physical_impacts_of_climate_change article is especially not satisfactory in this sense. There has been rich literatures investigating the general change of extreme precipitation, and the physical attributions to this change. I therefore propose to expand the sections that talk about precipitation extreme in the preexistent articles mentioned above into a main article named "Precipitation extreme and climate change".

Reliable sources could be the most recent journal articles that investigate the physical contributions to the change of precipitation extremes. There are at least 3-5 articles on this topic.

Proposed Project 2: Potential vorticity (2nd choice)

Wiki article Potential_vorticity has been categorized as stub article and hasn't been updated since 2011. One of the problems with it is it has no cited sources, which might cause text to be removed, said the warning from Wikipedia. I have several renowned and reliable sources that can add to this article, and I can also expand its scope.

Potential vorticity has been one of the most important wisdom in empirical weather predictions, and it's also one of the few theories that can elegantly explain various atmospheric phenomena. Therefore fortifying this article is crucial.

Proposed Project 3: QG Omega (1st choice)

It is an important diagnostic method to quantify vertical velocities from synoptic scale circulations. Currently it is requested in page https://en.wikipedia.org/wiki/Wikipedia:Requested_articles/Natural_sciences/Environment_and_geology#Meteorology.2Fweather as entry "Q-G Omega".
