World Extreme Weather Analysis Application in Python

In today’s era of climate change, understanding the correlation between climate shifts and extreme weather events is crucial. This analysis employs Python, a versatile programming language, to explore and visualize data associated with these events.

How Climate Change Exacerbates Extreme Weather Events

Climate change intensifies extreme weather events through various mechanisms. Rising global temperatures escalate the intensity and frequency of storms, heatwaves, floods, and droughts. For instance, the increased sea surface temperatures have fueled more powerful hurricanes like Katrina and Harvey, leading to devastating impacts.

Examples of Extreme Weather Events

  • Hurricanes: Hurricanes are among the most recognizable extreme weather events influenced by climate change. Warmer ocean waters provide more energy, resulting in stronger hurricanes with heavier rainfall and higher wind speeds.
  • Heatwaves: Heatwaves are becoming more frequent and severe. The European heatwave of 2019 saw record-breaking temperatures across the continent, impacting agriculture, health, and infrastructure.

Python

Python is favored in data analysis for its extensive libraries such as NumPy, and Pandas, and visualization tools like LightningChart Python. These resources facilitate efficient data handling, processing, and visualization, making Python indispensable for climate and weather analysis.

Bar Charts

The Bar Chart visualizes ‘Much Above Normal’ and ‘Much Below Normal’ temperature extremes across the United States from 1910 to 2021.

import pandas as pd
import lightningchart as lc

# Set license key
lc.set_license('my_license_key')

# Load data
data = pd.read_csv('ContiguousU.S.ExtremesInMaximumTemperature.csv')

# Prepare data for the combined Bar Chart
categories = data['Date'].astype(str).tolist()
data_combined = [
    {'subCategory': 'Much Above Normal', 'values': data['Much Above Normal'].tolist()},
    {'subCategory': 'Much Below Normal', 'values': data['Much Below Normal'].tolist()}
]

# Create the combined Bar Chart
bar_chart = lc.BarChart(
    vertical=True,
    theme=lc.Themes.White,
    title='Contiguous U.S. Extremes in Maximum Temperature'
)

# Set data for the combined Bar Chart
bar_chart.set_data_grouped(categories, data_combined)
