About Me

I am a master student in the School of Atmospheric Sciences, Sun Yat-sen University. I graduated from Chengdu University of Information and Technology with a bachelor's degree. My research involves climate change of extreme precipitation under global warming, machine learning, statistical model and complex network.

In my spare time, I like badminton, cycling, hiking, rock music and technology. This website will mainly share my favorite music, photos and bits and pieces of technical experience.

Research Interests

Extreme Preciptation: Gloabl Warming, Internal Atmospheric Variability, Future Changes.

Machine Learning: Residual Network, Attention Mechanism, Diffusion Model, et al.

import xarray as xr
import pandas as pd
import numpy as np
np.random.seed(0)
date = pd.date_range('2000-01-01', '2001-12-31', freq='D')
lon = np.arange(0, 360, 2.5)
lat = np.arange(-90, 92.5, 2.5)
data = xr.DataArray(data=np.random.rand(date.size, lon.size, lat.size), 
                    dims=['time', 'lon', 'lat'], 
                    coords=dict(time=date, lon=lon, lat=lat))

# 求 data 各月的最大值
## 法一 resample
mmax = data.resample(time='M').max()

## 法二 groupby
groupbins = xr.DataArray(data=data.indexes['time'].to_period('M').to_timestamp(), 
                         dims=['time'], coords=dict(time=data.time))
mmax = data.groupby(groupbins).max()
