How many degrees is a hot day, and how many degrees is above a hot day

Above 35 is considered a high temperature.

Even if the temperature exceeds 35, it is a high temperature. If the maximum temperature is above 35 for three consecutive days, the meteorological department of our country will issue a yellow warning signal for high temperature, so that the public can prepare for high temperature. So as long as it's more than 35, it's a high temperature. In summer, you can turn on the air conditioner and blow the fan.

There are three types of high temperature warning signals in China, except for yellow warning, orange warning, and red warning. The orange warning signal for high temperature means that the temperature rises above 37 within 24 hours, and the red warning signal for high temperature refers to the temperature rises above 40 within 24 hours.

High temperature precautions.

1.In hot weather, don't stay in the scorching sun. It is best not to go out from 12 noon to 2 pm.

2.Provide shade equipment on hot days, such as umbrellas and sunglasses, or choose a shady place. Apply sunscreen if possible.

3.Don't walk in the sun or go to crowded places. Don't blow the air conditioner right away when you get back to your room from outside.

4.Pay attention to food hygiene on hot days to prevent gastrointestinal discomfort and colds.

5.Pay attention to adequate sleep, regular life and rest, and enhance immunity.

6.When the weather is hot and you have symptoms such as dizziness, nausea, dry mouth, confusion, chest tightness and shortness of breath, you should rest immediately and drink some cold water to cool down. If the condition is severe, you should go to the hospital immediately**.

In China, the weather with a daily maximum temperature of 35 degrees or more is called a hot weather. The World Meteorological Organization (WMO) recommends that the maximum daily temperature be higher than 32 and last for more than 3 days.

In Chinese meteorology, it is generally called high temperature when the daily maximum temperature reaches or exceeds 35.

When the maximum temperature reaches 35 or above, it is a hot day.

High temperature warning: Yellow warning signal for high temperature: The temperature reaches 35 for three consecutive days Orange warning signal for high temperature: the temperature reaches 37 on the same day

Red warning signal for high temperature: The temperature reaches 40 on the day

35 or more.

Grading standard: The yellow warning signal standard for high temperature means that the daily maximum temperature will be above 35 for three consecutive days;

The high temperature orange warning signal standard means that the maximum temperature will rise above 37 within 24 hours;

The red warning signal for high temperature means that the maximum temperature will rise above 39 in 24 hours.

High temperature weather generally refers to the highest temperature of the day when it reaches or exceeds 35, which is called high temperature weather. If it is three or more days in a row, such a hot weather is called a high temperature heat wave. In such weather, it is necessary to pay more attention to heat stroke prevention and cooling.

39-40 degrees or more is a hot day.

When the temperature is above 35, it can be called "hot weather", and if the maximum temperature exceeds 35 for several consecutive days, it can be called "high temperature and heat wave" weather. Generally speaking, there are usually two situations of high temperature, one is dry heat high temperature with high temperature and low humidity. The other is the sultry heat with high temperatures and high humidity, which is called "sauna days".

The formation of high temperatures is often directly caused by specific weather systems, the most typical and common of which is the subtropical high, which has the title of "high temperature messenger". In addition to natural factors, the formation of hot weather is also affected by human activities.

Causes of formation:

1. Weather system triggering: The formation of high temperature is often directly caused by a specific weather system, the most typical and common of which is the subtropical high with the title of "high temperature messenger". In addition to the subtropical high, the air-containing systems of Tianheng dust, such as the continental warm high pressure, tropical cyclone, thermal low pressure, and weak cold front, will also give rise to high temperature and heat waves.

2. Global warming provides climate background: Under the influence of global warming, extreme heat events are becoming more and more frequent.

3. The urban heat island effect "adds fuel to the fire": The urban heat island effect refers to the phenomenon that the temperature in the center of the city is higher than that in the suburbs. With the acceleration of urbanization, the urban heat island effect has become more obvious, which undoubtedly plays a role in contributing to the hot weather.
