Take the summer solstice as an example: the direct point of the sun on the summer solstice is 23°26 n, the latitude of Beijing is 40°, and the latitude of Guangzhou is about 23°.

The noon solar altitude of the two places is: 90°-|40°-23°26′|= 73°26 on the southern slope of the mountain with a slope of 17 in Beijing, the height of the sun at noon is close to 90°. The noon solar height above the horizontal plane of Guangzhou is 90°-|23°-23°26′|= 89°34, close to 90°.

The height of the sun at noon is close, and the intensity of solar radiation obtained at noon is relatively close.

Beijing: 39 degrees 54 minutes north latitude, 116 degrees 23 minutes east longitude.

Guangzhou: 23 degrees 06 minutes 32 seconds north latitude, 113 degrees 15 minutes 53 seconds east longitude.

Just take a look at it.

At the same time, the noon solar altitude of the southern slope of the mountain is +17° of Beijing, because Beijing is 40° north latitude, so the solar altitude angle of the southern slope is equivalent to 40°-17°=23°, that is, 23° north latitude, which is roughly the Tropic of Cancer, and Guangzhou happens to be in the approximate position.

This question should be understood in this way: first of all, it is seen that its terrain slope is 17, which is relatively low and flat, and the light intensity will be relatively large, and then it is located on the southern slope, so it can be affected by the southeast monsoon, so the answer is Guangzhou.

Between 40-60 north latitude is the westerly climate, look at the map in Madrid and Barcelona belongs, and Valencia although between 30-40 north latitude, but located on the east coast of the continent, is also a westerly climate, the annual precipitation of the westerly climate is characterized by the four seasons are relatively average, and Seville is between 30-40 north latitude, and is located on the west coast of the continent, belongs to the Mediterranean climate, the annual precipitation of this climate is characterized by more rainfall in winter, accounting for about 60-70% of the total of the year, so choose Seville.

rateThe meaning is the point.

The rate is a ratio, not by the size of the quantity, but by the size of the numerator and the denominator compared to the result (percentage).

Details:

The winter rainfall rate is the percentage of winter precipitation in the annual precipitation, and the area shown is a Mediterranean climate zone with hot and dry summers.

According to the diagram, among the four options,"Seville has the highest rate of winter rainfall".This is because:

1. Seville is located in the south, and the westerly wind belt is the shortest in winter, although the winter rainfall is the least, but the proportion of winter precipitation is the largest, so the winter rainfall rate is the highest.

2. Although Barcelona, Madrid and Valencia have a large amount of winter rainfall, they have more annual precipitation, so the winter rainfall rate is low.

According to the above analysis: the answer is D.

Madrid and Valencia are above 40 north latitudes, typical westerly climate, Valencia is on the east coast of the continent, it is also a westerly climate, and Seville is a Mediterranean climate, (west coast of the continent, 30-40 north latitude), one of the remarkable characteristics of the Mediterranean climate is that the winter rainfall accounts for 60-70 of the year, so Seville has the highest winter rain rate.

Question: Winter rainfall rate refers to the ratio of winter rainfall to the whole year, Barcelona has a relatively average annual rainfall rate, so the winter rainfall rate is small, while Seville has a Mediterranean climate and is in the interior of the continent, so the winter rainfall rate is high.

The sun in the northern hemisphere is obliquely radiated, and the direct point is in the southern hemisphere, so the amount of solar radiation received by the northern hemisphere is less and the time is shorter, so the temperature is relatively cold, which is winter.

The image is too small, I took a screenshot of the original question:

Question 1: Since the mountain peak in the figure is the highest peak in the region, there must be a closed contour line nested around the peak, so P and Q pass through the same contour line. The points (m, n) on the ridgeline on the periphery of P and Q do not rule out the existence of small areas of closed contours on the side of the ridge.

As shown in the figure below:

Therefore, the elevations of M and N are not necessarily equal, so choose [A].

Question 2: According to the principle of the first question, considering the various possibilities of contour distribution, it is concluded that there are many possibilities for the relative height of A and B. Since A is located near the highest peak, its altitude range is fixed, i.e. (3600, 3652), and the multiple possibilities of the contour distribution lead to the following cases of the altitude range of B:

In summary, option [a] of this question is not possible.

The answer is very clear, brother.

This is an incomplete diagram, ok after completing the contours

I think the analysis is quite clear.

The diagram shows the Northern Hemisphere, where arrow A is the direction of the pressure gradient force and arrow B is the direction of the wind. A is northeasterly, B is southwesterly or westerly.

In northeastern Asia, the outer ring to the inner ring decreases, so it is known that this is the center of low pressure, and high pressure points to low pressure. Make a tangent line at the circle where A and B are located, and then make a perpendicular line on the tangent line, the high pressure points to the low pressure, and because of the deflection force of the ground, ("south left, north right, palm facing yourself") The direction pointed by the thumb is the wind direction.
