What is the difference between high and low temperatures

The climate of India is hotter than that of England. Winter lasts from December to February. In April, there were four western disturbances, of which one caused widespread rain and snow over northern hilly states in April. Moisture was pulled over from Arabian Sea to the land, bringing widespread clouding and rainfall over Kerala, Karnataka and Maharashtra.

The best time to visit India is between October and March, when the weather is more likely to be warm, sunny, and dry. During this time, the north offers clear blue skies. However, December and January are much cooler, with potential fog, while the higher Himalaya can be very cold, but with clearer mountain views.

This graph shows the percentage of the land area of the contiguous 48 states with unusually hot daily high and low temperatures during the months of June, July, and August. The thin lines represent individual years, while the thick lines show a nine-year weighted average. Red lines represent daily highs, while orange lines represent daily lows. This graph shows the percentage of the land area of the contiguous 48 states with unusually cold daily high and low temperatures during the months of December, January, and February.

Blue lines represent daily highs, while purple lines represent daily lows. This map shows trends in unusually hot temperatures at individual weather stations that have operated consistently since The map shows changes in the total number of days per year that were hotter than the 95 th percentile.

Red upward-pointing symbols show where these unusually hot days are becoming more common. Blue downward-pointing symbols show where unusually hot days are becoming less common. This map shows trends in unusually cold temperatures at individual weather stations that have operated consistently since The map shows changes in the total number of days per year that were colder than the 5 th percentile. Blue upward-pointing symbols show where these unusually cold days are becoming more common.

Red downward-pointing symbols show where unusually cold days are becoming less common. This figure shows the percentage of daily temperature records set at weather stations across the contiguous 48 states by decade. Record highs red are compared with record lows blue. Data source: Meehl et al. Unusually hot or cold temperatures can result in prolonged extreme weather events like summer heat waves see the Heat Waves indicator or winter cold spells.

Heat waves can lead to illness and death, particularly among older adults, the very young, and other vulnerable populations see the Heat-Related Deaths and Heat-Related Illnesses indicators. In addition, prolonged exposure to excessive heat and cold can damage crops and injure or kill livestock.

Extreme heat can lead to power outages as heavy demands for air conditioning strain the power grid, while extremely cold weather increases the need for heating fuel. Record-setting daily temperatures, heat waves, and cold spells are a natural part of day-to-day variation in weather.

Conversely, cold spells are expected to decrease. In most locations, scientists expect daily minimum temperatures—which typically occur at night—to become warmer at a faster rate than daily maximum temperatures. The data come from thousands of weather stations across the United States.

National patterns can be determined by dividing the country into a grid and examining the data for one station in each cell of the grid. This method ensures that the results are not biased toward regions that happen to have many stations close together. These graphs are based on daily maximum temperatures, which usually occur during the day, and daily minimum temperatures, which usually occur at night. At each station, the recorded highs and lows are compared with the full set of historical records.

Data are available from to for summer June through August and from to for winter December of the previous year through February. Figures 3 and 4 show how trends in unusually hot and cold daily temperatures throughout the year vary by location.

These maps cover about 1, weather stations that have operated since Figure 3 was created by reviewing all daily maximum temperatures from to and identifying the 95 th percentile temperature a temperature that one would only expect to exceed in five days out of every at each station.

Next, for each year, the total number of days with maximum temperatures higher than the 95 th percentile that is, unusually hot days was determined.

The map shows how the total number of unusually hot days per year at each station has changed over time.
