I could see that many blaming that the best Javelin-throw athletes failed to perform well, hence a normal Neeraj Chopra won the Gold. While it may look odd, i have done some research and presenting my analysis below,
1) what are the windspeed, temperature and weather when Neeraj got his gold medal?
Event happened on 7-August-2021 around 6PM to 7PM Japanese time, Tokyo Olympic stadium, find the weather on that day below,

2) What are the same parameters when Vetter ( other top performing athlete in this sport) had their personal best ?
Below is the windspeed when he threw ~97meter to win the championship at
Kamila Skolimowska Memorial at Silesian Stadium in Chorzów, Poland .

He came 5th in 2018 European Athletics Championships, were held in Berlin, Germany, below is the weather:
Thursday, 9 August 2018, 12:00 — 18:00
Temp : 34 / 30 °C

Finally his last appearance before TokyoOlympics2020 as far as i know was in Doha, Even in doha the conditions were similar and he could throw only ~85meter.
3) Same parameters to be analysed during the training of last one year for all the players, Here we need to do for Neeraj vs Vetter.
I do not have this data.
4) Finally, how do these parameters affect the performance on distance?
This document has some good explanation :
